Boy Names That Start With B: 147 Ideas

Boy names that start with B run from classics like Benjamin, Bennett and Brooks to rare picks like Barnaby, Bevis and Boone, and this list of 147 gives a checked origin and meaning for every one.

B is a warm, sturdy letter for naming a son. It holds one of the oldest names in use (Benjamin), English surname favorites (Brooks, Beckett, Bennett), a whole family of bear names, Norse gods, Arthurian knights and names from languages around the world. None of the B names is in the Social Security Administration top 10 for boys born in 2025, so even a familiar choice stays a little less common.

We grouped the B boy names by style: classic, unique, strong, short, long, vintage, nature, mythology, biblical, international and gender neutral. Then come name families and nicknames, sibling and middle name ideas, and a quick initials check.

Key Takeaways

No B name is in the U.S. top 10 for boys born in 2025, so classics like Benjamin, Bennett, Brooks and Beckett feel familiar without being overused.
Rare B names include Barnaby, Barclay, Bevis, Beauregard, Booker and Boone, several of which Behind the Name marks as rare in English.
Strong B names include Baldwin (“bold friend”), Brock (“badger”), Burke (“fortress”), Bahadur (“hero, warrior”) and Batu (“strong, firm”).
Some well known B names, such as Brian, Boris and Brennus, have an uncertain or only possible meaning, and an honest list says so.
Test your favorite with the initials, say it out loud and nickname checks before you decide.

Boy Names That Start With B at a Glance

Quick Answer

Standout B names for boys: Benjamin, Bennett, Brooks, Beckett, Bryson, Brody and Bradley (familiar); Barnaby, Booker, Boone and Bevis (rare); Baron, Brock, Baldwin and Batu (strong); Bo, Ben, Bram and Brett (short); Bear, Björn, Brennan and Bora (nature). No B name is in the U.S. top 10 for boys born in 2025, so even the classics here stay a little less crowded.

Every origin and meaning on this page was checked against the name’s own entry on Behind the Name in October 2026. Where the reference calls a meaning unknown, uncertain, possible or probable, we say so too.

How to read the tables: the Origin column uses the reference’s own usage labels, so “English (rare)” and “English (modern)” are its words, not ours. When the Meaning column says a name is a form, variant or short form of another name, that is all the entry states, and the root name is usually elsewhere on this page with its own meaning.

We start with the most familiar baby boy names that start with B. For ideas beyond a single letter, see our full list of baby boy names.

Familiar and classic B boy names with origins and meanings.

The Social Security Administration (SSA) top 10 for boys born in 2025 is Liam, Noah, Oliver, Theodore, Henry, James, Elijah, Mateo, William and Lucas, so none of the best known B names is in it. That is good news if you want a name people already know how to spell, but that you will not hear called across the playground five times a day.

A few notes on the table. Benjamin is the oldest name here. In the Old Testament he is the twelfth and youngest son of Jacob, and Behind the Name notes that his mother Rachel first named him Ben-oni, “son of my sorrow,” before his father changed it. Bennett is simply a medieval form of Benedict, and the reference says it was the more common spelling in England until the 18th century.

Many of the familiar B names are English surnames that began as descriptions of a landscape: Brandon is a “hill covered with broom,” Bradley a “broad clearing” and Bentley a clearing where bentgrass grew. Brooks and Beckett may both point to a stream. Brian is a good example of honest uncertainty: the reference calls its meaning uncertain and offers two possible Celtic roots, one for “hill, high” and one for “might, power.”

The SSA ranks every spelling separately. Its background notes say different spellings of similar names are not combined, so Brayden and Braden, or Brody and Brodie, each get their own rank, and one sound can be more common than any single spelling suggests.

Unique, Rare and Strong Boy Names That Start With B

If you want unique boy names that start with B, the old English and Scottish surnames are a rich seam. Behind the Name marks several of the names below as rare in English, yet all of them are easy to read and say.

Name	Origin	Meaning
Barnaby	English (British)	English form of Barnabas, originally a medieval vernacular form
Booker	English	From an English occupational surname: “maker of books”; borne by Booker T. Washington
Boone	English	From an English surname, either from Old French bon, “good,” or from the town of Bohon, France
Barclay	English (rare)	From a Scottish and English surname taken from the place name Berkeley: Old English beorc, “birch,” plus leah, “woodland, clearing”
Bevis	English (rare)	From an English surname, possibly from the name of the French town Beauvais
Baxter	English	From an occupational surname: “(female) baker,” from Old English bæcere plus a feminine suffix
Beauregard	English (rare)	From the French surname Beauregard: “beautiful aspect”
Bridger	English (modern)	From an English surname for a person who lived near or worked on a bridge
Bishop	English	From the occupational surname or the English word, ultimately from Greek episkopos: “overseer”
Boyd	English	From a Scottish surname, possibly from the name of the island of Bute (Bód in Gaelic)

Unique and rare B names for boys.

Most of these began as last names that described a job or a place. Booker meant a maker of books, Baxter a baker and Bridger someone who lived near or worked on a bridge. Barclay comes from Berkeley, an English place name built on the words for “birch” and “clearing.” Barnaby is the gentle exception: it is the English form of the New Testament name Barnabas, and the reference says it is still moderately common in Britain.

To check how rare a name really is, use the Popularity of a Name search on the SSA baby names page. The SSA leaves out names with fewer than 5 occurrences in any geographic area to protect privacy, so the very rarest names never show up in its lists at all. For more ideas, see our unique boy names guide.

For strong boy names that start with B, meaning is the best guide. This letter has a baron, a badger (Brock), a fortress (Burke), a “bold friend” (Baldwin), a hero and warrior (Bahadur) and two names that simply mean strong: Batu in Mongolian and Berk in Turkish. Our strong boy names list covers every letter.

Name	Origin	Meaning
Baron	English	From the noble title, from Latin baro: “man, freeman,” probably ultimately of Frankish origin
Brock	English	From an English surname, from Old English brocc: “badger”
Baldwin	English, Germanic	“Bold friend,” from Old German bald, “bold, brave,” and wini, “friend”; a leader of the First Crusade
Bronson	English (modern)	From an English surname: “son of the brown one”
Burke	English	From an English surname, from Old English burg: “fortress”
Brennus	Gaulish (Latinized)	Possibly “king, prince” or “raven”; a Gallic leader of the 4th century BC who sacked Rome
Brutus	Ancient Roman	Roman cognomen meaning “heavy” in Latin
Bahadur	Hindi, Nepali	From Persian bahādor, from Turkic bagatur: “hero, warrior”; borne by rulers of the Mughal Empire
Batu	Mongolian	“Strong, firm”; Batu Khan was a 13th century Mongol leader
Berk	Turkish	“Solid, firm, strong”
Boris	Bulgarian, Russian, Slovene, Croatian, Serbian, Czech, German, French and more	From a Bulgar Turkic name, perhaps meaning “short,” “wolf” or “snow leopard”; borne by the 9th century saint Boris I of Bulgaria

Strong and cool B names for boys.

Two of these come with honest question marks. For Brennus, the Gallic leader who sacked Rome in the 4th century BC, the reference says the name possibly meant “king, prince” or “raven.” For Boris it offers three guesses: “short,” “wolf” or “snow leopard.” We print both exactly that way rather than picking the most flattering option.

Short B Names for Boys (2 to 5 Letters)

Short B names fit neatly on a cubby label, are hard to shorten further and pair easily with a long surname. Several began as nicknames and now stand on their own. Our short boy names guide has more ideas from every letter.

Name	Origin	Meaning
Bo	Swedish, Danish	From the Old Norse byname Búi, from bua: “to live”
Ben	English, German, Dutch	Short form of Benjamin, Benedict and other names beginning with Ben
Bob	English, Dutch	Short form of Robert
Bill	English	Short form of William
Bert	English, German, Dutch	Short form of Albert and other names containing bert, often from Old German beraht, “bright”
Burt	English	Short form of Burton
Bud	English	Short form of Buddy
Bram	English, Dutch	Short form of Abraham; borne by Bram Stoker, author of Dracula
Brett	English	From an English surname: “a Breton,” someone from Brittany
Brent	English	From an English surname taken from place names, perhaps from a Celtic word for “hill”
Bodo	German, Germanic	From Old High German bot: “command, order”; a 7th century saint and bishop of Toul
Brice	French, English	From Bricius, probably a Latinized form of a Gaulish name meaning “speckled”; a 5th century saint

Short boy names starting with B.

Notice how many short B names are nicknames of longer names that start with a different letter. Bob is short for Robert, Bill for William, Bert for Albert and Bram for Abraham. So if you love the short form, you have a choice: give it on its own, or put the longer name on the birth certificate and use the short one every day.

Others are full names with their own history. Bo, in its Swedish and Danish use, comes from an Old Norse byname meaning “to live.” Brice goes back to a Gaulish name probably meaning “speckled” and was borne by a 5th century saint. Bodo, a German name, means “command, order.” More short names live in other tables: Ber, Bear and Buck in the nature table, Boaz in the biblical table, and Bao, Bin, Blue and Bryn in the gender neutral table.

Long, Elegant and Vintage B Names

Longer B names give a formal option for later in life and, often, a ready nickname for the early years.

Name	Origin	Meaning
Bartholomew	English, biblical	From the Greek form of an Aramaic name meaning “son of Talmai”; the byname of an apostle (New Testament)
Benedict	English	From the Latin name Benedictus: “blessed”; Saint Benedict founded the Benedictines in the 6th century
Bonaventure	French, History (ecclesiastical)	French and English form of Bonaventura; used in English mostly in reference to the saint
Boniface	French, English (rare)	From the Latin name Bonifatius: “good fate,” from bonus, “good,” and fatum, “fate, destiny”
Bertrand	French, English, Germanic	Old German beraht, “bright,” plus rant, “rim (of a shield)”; long confused with Bertram
Bertram	English, German, Germanic	“Bright raven,” from Old German beraht, “bright,” and hram, “raven”
Bradford	English	From a surname and place name: “broad ford” in Old English

Long and elegant B boy names.

Bertram and Bertrand are a famous pair of look alikes. Bertram means “bright raven” and Bertrand joins “bright” with the rim of a shield, but Behind the Name says the two have been confused from an early date and have merged to some degree. Benedict, “blessed,” was used by 16 popes, and Boniface, “good fate,” by nine. Bartholomew is the byname of an apostle and, per the reference, may be the same person as the apostle Nathanael.

These vintage picks feel familiar from parents’ and grandparents’ generations. Several are pet forms that were given as full names. If you like this style, our old fashioned boy names list has many more.

Name	Origin	Meaning
Barry	Irish, English	Anglicized form of Barra; popular across the English speaking world in the middle of the 20th century
Bernard	English, French, Dutch, Polish, Croatian, Slovene, Czech, Germanic	Old German bern, “bear,” plus hart, “hard, firm, brave, hardy”
Basil	English	From the Greek name Basileios: “royal, kingly”; Saint Basil the Great was a 4th century bishop
Burton	English	From an English surname and place name: “fortified town” in Old English
Byron	English	From a surname and place name: “place of the cow sheds” in Old English; the surname of the poet Lord Byron
Buddy	English	From the English word for “friend,” probably first a nursery form of “brother”
Bobby	English	Diminutive of Bob
Billy	English	Diminutive of Bill
Barney	English	Diminutive of Barnabas, Bernard or Barnaby
Benny	English	Diminutive of Benjamin or Benedict

Vintage and old fashioned B names for boys.

Bernard is a nice bridge between the vintage and nature styles: it joins the Old German words for “bear” and “brave, hardy.” Basil, from Greek, means “royal, kingly,” and Buddy, which sounds so modern and casual, is listed as an English word for “friend” that probably started as a nursery form of “brother.”

Nature B Names: Bears, Rain and Storms

These names connect to the natural world through their stated meaning. The letter B has an unusual number of bears, plus a deer, rain, lightning and a storm. Briar, Brook, Bryn (“hill, mound”), Blue and Baran (“rain”) also belong here, but you will find them in the gender neutral table, since the reference lists them for both boys and girls.

Name	Origin	Meaning
Bear	English (modern)	From the English word for the animal, from Old English bera, probably from a root meaning “brown”
Buck	English	From an English nickname: “buck, male deer,” from Old English bucc
Björn	Swedish, Icelandic, German	From an Old Norse byname, from bjǫrn: “bear”
Bjarne	Danish, Norwegian, Swedish	Modern form of Bjarni, an Old Norse diminutive of Bjǫrn and names containing bjǫrn, “bear”
Ber	Yiddish	“Bear” in Yiddish, a vernacular form of Dov
Benno	German	Short form of German names containing the element bern, “bear”
Brennan	English	From an Irish surname based on Irish braon: “rain, moisture, drop,” plus a diminutive suffix
Benton	English	From a surname and place name: Old English beonet, “bentgrass,” plus tun, “enclosure”
Burak	Turkish	From Arabic Burāq, the legendary creature of Islamic tradition; the name comes from barq: “lightning”
Bora	Turkish	“Storm, squall” in Turkish; possibly Turkic, though it might be related to Greek Boreas

Nature inspired B names for boys.

The bear family is worth a closer look. Bear is the plain English word. Björn is the Old Norse byname, and Bjarne is a modern form of an Old Norse diminutive of it. Ber is the Yiddish word, a vernacular form of the Hebrew name Dov. Benno is a German short form of names containing bern, the same element found in Bernard. Even Beowulf, in the mythology table, possibly means “bee wolf,” which the reference reads as a poetic way of saying “bear.”

The weather names are just as vivid. Brennan comes from an Irish word for “rain, moisture, drop.” Burak traces to the Arabic word for “lightning,” and Barak, in the biblical table, means “lightning” in Hebrew. Bora is a Turkish word for “storm, squall” that might be related to Boreas, the Greek north wind. Several English names on this page hide plants, too: Bentley and Benton both contain the Old English word for bentgrass, and Brandon contains the word for broom.

Mythology, Literature and Biblical B Names

Norse, Welsh, Greek and Anglo-Saxon stories all supply B names, and so do Shakespeare and Tolkien. Where the reference gives only a possible or probable meaning, as it does for Bellerophon, Bedivere, Bors and Beowulf, we print it that way.

Name	Origin	Meaning
Balder	Norse mythology	From Old Norse Baldr: “hero, lord, prince,” from baldr, “brave, bold”; the son of Odin and Frigg
Bragi	Norse mythology, Icelandic	From Old Norse bragr: “first, foremost” or “poetry”; the Norse god of poetry
Brân	Welsh mythology	“Raven” in Welsh; Brân the Blessed, a giant king of Britain in the Second Branch of the Mabinogi
Boreas	Greek mythology	“North wind” in Greek; the Greek god of the north wind
Bellerophon	Greek mythology	Possibly from Greek belos, “dart,” plus a suffix meaning “slayer of”; the hero who tamed Pegasus
Bacchus	Greek mythology (Latinized)	From Greek Bakchos, from iacho: “to shout”; another name of the god Dionysos
Bedivere	Welsh mythology, Arthurian cycle	From Welsh Bedwyr, possibly “birch” plus “man”; the knight who throws Excalibur into the lake
Bors	Arthurian cycle	Probably from Old French behort or bohort: “jousting” or “jousting lance”; a knight of the Grail quest
Beowulf	Anglo-Saxon mythology	Possibly “bee wolf” (in effect “bear”), or the first part may be beadu, “battle”; hero of the 8th century epic poem
Bilbo	Literature	The hero of The Hobbit (1937) by J. R. R. Tolkien; his “real” hobbit name, Bilba, is of unknown meaning
Benvolio	Literature	“Good will” in Italian; a friend of Romeo in Shakespeare’s Romeo and Juliet (1596)

B names from mythology, legend and literature.

Balder is the beloved son of Odin and Frigg in Norse mythology, and his German and Icelandic form, Baldur, is in the international table. Bragi is the Norse god of poetry. On the Welsh side, Brân the Blessed is a giant king in the Mabinogi, and Bedivere is one of the original companions of King Arthur, the knight who throws the sword Excalibur into the lake. For Bilbo, the reference is refreshingly frank: Tolkien’s hobbit name Bilba is of unknown meaning.

For biblical boy names that start with B, the best known is Benjamin from the first table. Bartholomew, in the long names table, is the byname of an apostle. Less common choices:

Name	Origin	Meaning
Boaz	Biblical, Hebrew, Dutch	“Swiftness” in Hebrew; the man who marries Ruth (Old Testament)
Barnabas	German (rare), English (rare), biblical	Greek form of an Aramaic name, perhaps “son of the prophet,” though Acts says it means “son of encouragement”; a companion of Paul (New Testament)
Baruch	Biblical, Hebrew	From Hebrew Baruḵ: “blessed”; the scribe and companion of the prophet Jeremiah (Old Testament)
Barak	Hebrew, biblical	“Lightning” in Hebrew; a military commander who served with the prophetess Deborah (Old Testament)
Benaiah	Biblical	From Hebrew Benaya: “Yahweh has built”; the name of numerous Old Testament characters
Balthazar	Judeo-Christian-Islamic legend	Variant of Belshazzar; the name traditionally given to one of the wise men who visited the newborn Jesus

Biblical B names for boys.

Barnabas has a lovely detail: the original Aramaic form is unattested, and it may mean “son of the prophet,” but the Book of Acts itself says the name means “son of encouragement.” Balthazar does not appear in the Bible as one of the wise men; the reference lists it under legend, as the name tradition later gave to one of them. See our biblical boy names guide for more names from the Old and New Testaments.

International B Names by Language

The origin labels below are the reference’s own usage labels. Where an entry says only that a name is a form of another name in a given language, we print exactly that and point you to the root name on this page.

Branimir	Croatian, Serbian, Bulgarian, Slovene	Slavic borna, “protection,” plus mirŭ, “peace, world”
Brendan	Irish, English, Breton	From Brendanus, the Latinized form of Old Irish Bréanainn, from Old Welsh breenhin: “king, prince”; a 6th century Irish abbot

European B names for boys, grouped by language.

Three name families do much of the work here. Benedetto, Benoît and Benedikt are all forms of Benedict, “blessed.” Bernardo and Bernhard come from Bernard, the bear name. Baptiste and its Spanish form Bautista honor Saint John the Baptist. Bastian and Bastien are short forms of Sebastian and Sébastien, and Bartosz is the Polish form of Bartholomew.

Name	Origin	Meaning
Bilal	Arabic, Turkish, Urdu, Kyrgyz	“Wetting, moistening” in Arabic; a companion of the Prophet Muhammad
Bashir	Arabic, Urdu	“Bringer of good news, herald” in Arabic
Basim	Arabic	“Smiling” in Arabic

Bhaskar	Hindi, Marathi, Telugu, Kannada	Modern form of Bhaskara: “shining, light maker,” another name of the sun god Surya
Baraka	Swahili	“Blessing” in Swahili, ultimately from Arabic baraka
Bakari	Swahili	From the Swahili name for the constellation Boötes
Bongani	Zulu	“Grateful, thankful” in Zulu
Babatunde	Yoruba	“Father has come again” in Yoruba

Arabic, Persian, Turkish, South Asian and African B names.

Several of these are complete, warm words in their own languages: Bashir is “bringer of good news,” Basim “smiling,” Baraka “blessing,” Bongani “grateful, thankful” and Bayram “festival, holiday.” Babatunde, “father has come again,” is a Yoruba name, and Bakari comes from the Swahili name for a constellation. Bharat and Bhaskar are modern forms of Sanskrit names: Bharata, “being maintained,” and Bhaskara, “shining, light maker.”

Print accents and special letters exactly as the name is spelled: Björn, Brân, Benoît, Beltrán and Bálint. U.S. paperwork does not always carry accents or special characters, so decide ahead of time whether you are comfortable seeing the name without its mark on some documents. If a name comes from a culture outside your own family, take time to learn how it is said and used before you commit.

Gender Neutral B Names

Behind the Name lists each of these as both masculine and feminine. Many began as English or Scottish surnames, and a few come from Chinese, Arabic, Persian, Turkish and Kurdish. You will find more in our gender neutral names guide.

Name	Origin	Meaning
Blake	English	From a surname, from Old English blæc, “black,” or blac, “pale”
Beau	English, Dutch (modern)	“Beautiful, handsome” in French; used as a given name since the middle of the 20th century
Bailey	English	From a surname, from Middle English baili: “bailiff”
Blair	Scottish, English	From a Scottish surname, from Gaelic blàr: “plain, field, battlefield”; typically masculine in Scotland
Bellamy	English (modern)	From a surname, from Old French bel ami: “beautiful friend”
Bowie	English (modern), Dutch (modern)	From a Scottish surname, from Gaelic buidhe: “yellow”
Briar	English (modern)	From the English word for the thorny plant
Brook	English	From a surname for someone who lived near a brook
Bryn	Welsh, English (modern)	“Hill, mound” in Welsh; in Wales it is almost always a masculine name
Blue	English (rare)	From the English word for the color
Bao	Chinese	From Chinese characters meaning “treasure, jewel, precious,” “praise, honor” or “bud,” among others
Bin	Chinese	From Chinese characters meaning “refined” or “guest,” among others
Badr	Arabic	“Full moon” in Arabic
Baran	Persian, Turkish, Kurdish	“Rain” in Persian; typically feminine in Persian and masculine in Turkish and Kurdish

Gender neutral names that start with B.

The reference adds context for a few. Blair is typically masculine in Scotland, and Bryn is almost always masculine in Wales. Baran is typically feminine in Persian but masculine in Turkish and Kurdish. For the Chinese names Bao and Bin, the meaning depends on the character chosen, and the reference notes that other characters are possible as well.

Why B Names Are Loved: Sound, Spelling and Nicknames

B gives a name a warm, sturdy start. A few plain reasons parents keep coming back to this letter:

The sound is soft but clear, and it works with almost any vowel: Bo, Ben, Bear, Brice, Bruno.
The range is wide: one syllable (Brock, Brooks, Bram) to four or more (Bartholomew, Bellerophon, Bonaventure), ancient (Brutus, Brennus) to modern (Braylon, Bodhi).
The meanings are appealing. “Blessed” (Benedict, Baruch), “blessing” (Baraka), “given by God” (Bogdan), “bold friend” (Baldwin) and “beautiful friend” (Bellamy) all sit under this letter.
The big B names travel well. Benedict, Bernard and Bartholomew each have a matching form in several languages.

That last point is easier to see as families. Each line groups names the reference links to one another:

The Benedict family: Benedict, Bennett, Benedetto, Benoît and Benedikt.
The Bernard family: Bernard, Bernardo, Bernhard and Barney.
The Bartholomew family: Bartholomew and Bartosz.
The Balthazar family: Balthazar and Baltasar.
The Balder family: Balder and Baldur.
The Brice family: Brice, Bryce and Bryson (“son of Brice”).

If a relative carries one of these names, another member of the same family is a quiet way to honor them without repeating the name exactly. A grandfather named Bernard could inspire a Bernardo; a great uncle Benedict could become a Bennett.

Full name	Nickname ideas
Benjamin, Benedict	Ben, Benny
Bernard	Barney, and in German Benno (a short form of names containing bern, “bear”)
Barnabas, Barnaby	Barney
Burton	Burt
Bertram, Bertrand	Bert (a short form of names containing bert)
Buddy	Bud
Bill	Billy
Bob	Bobby

Nickname ideas for B names, each listed as a short form or diminutive on Behind the Name.

Sibling, Twin and Middle Name Ideas

These pairings are ideas, not rules. Brother or twin sets that share a letter work best when the names differ in length, ending or rhythm, so the two are not confused when you call up the stairs:

Benjamin and Brooks
Bennett and Beau
Beckett and Bowen
Barnaby and Booker
Bruno and Benicio
Björn and Birger
Bashir and Bilal
Brân and Bedivere
Bear and Briar
Boaz and Baruch

You can also link siblings through meaning instead of sound. Björn and Bernard both carry the bear. Burak and Barak both mean “lightning.” Benedict and Baruch both mean “blessed,” and Brennan and Baran both point to rain.

For a sister, the unisex picks Blair, Bailey, Briar and Bellamy keep the letter, or you can match from our girl names that start with B. For a brother with a different initial, try boy names that start with N.

For middle names, contrast helps. A short first name can carry a longer middle, a long first name is balanced by a short one, and a middle that starts with a different sound keeps the two from running together. Ideas: Beau Theodore, Brooks William, Bennett James, Bodhi Henry, Benjamin Elijah and Bram Oliver. B names also make easy middle names themselves: Blake, Bryce, Beau, Benedict and Bennett all sit comfortably in the second slot.

The Initials Check and Other Quick Tests

Before you settle on boy names that start with B, run each finalist through four quick tests:

Initials: write out first, middle and last initials. B.E.N. and B.E.A.U. are charming. B.A.D. and B.O.O. are not, so swap the middle name if you spot a problem.
Say it out loud: call the full name across a room. A first name that ends in an S or N sound (Brooks, Brandon, Bryson) can blur into a surname that starts with the same sound, so listen for the break.
Spelling: if there are several spellings (Brice and Bryce, Brayden and Braden, Brook and Brooks, Bastian and Bastien), decide whether you mind correcting people.
Nicknames: check the nickname table above. If you dislike the obvious short form (Barney for Bernard, Bobby for Bob, Burt for Burton), assume someone will use it anyway.

One more check is worth a minute if rarity matters to you: the SSA also publishes name data by state, so look up your favorite for your own state as well as nationally.

The Bottom Line

The letter B covers nearly every style: timeless classics like Benjamin and Bennett, surname picks like Brooks and Beckett, rare finds like Barnaby, Bevis and Boone, and names from Norse, Welsh, Hebrew, Arabic, Persian, Turkish, Mongolian, Sanskrit, Swahili, Zulu and Yoruba. None of them sits in the current U.S. top 10, so even the familiar ones will not feel overused. Shortlist three to five, check the meaning, test the initials and say each one out loud for a week.
