D is a steady, friendly letter for naming a son. It holds some of the oldest names in use (Daniel and David), Irish and Welsh favorites (Declan, Desmond, Dylan), dragon names, saints, poets and names from languages around the world. None of the D names is in the Social Security Administration top 10 for boys born in 2025, so even a familiar choice stays a little less common.

Boy Names That Start With D at a Glance

Quick Answer

Standout D names for boys: Daniel, David, Dylan, Dominic, Declan, Damian and Diego (familiar); Dashiell, Diggory, Dunstan and Dacre (rare); Drake, Duke and Donald (strong); Dax, Dex and Dash (short); Dekel, Dror and Doruk (nature). No D name is in the U.S. top 10 for boys born in 2025, which leaves this letter classic but 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 D. For ideas beyond a single letter, see our full list of baby boy names.

Damian	English, Polish, Romanian, Dutch (modern)	From Greek Damianos, from damazo: “to tame”; a 4th century saint and patron of physicians

Dante	Italian	Medieval short form of Durante; borne by the poet Dante Alighieri, author of the Divine Comedy

Familiar and classic D 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 D names is in it. That is good news if you want a name that everyone can spell and say, but that you will not hear called out five times at the playground.

A few notes on the table. Daniel and David are two of the oldest names on this page: both come from Hebrew and both belong to major figures in the Old Testament. Dawson and Davis grew out of surnames that meant “son of David,” or simply came from David. Damian and Damon share a Greek root, damazo, meaning “to tame.” And Declan is a good example of honest uncertainty: the reference says the meaning is unknown, though the name likely begins with an Old Irish word for “good.”

Dylan carries one of the prettiest stories here. In the Welsh Mabinogi, Dylan was a son of Arianrhod who went to the sea right after his baptism. Behind the Name gives the Welsh pronunciation as /ˈdəl.an/ and the English one as /ˈdɪl.ən/, so the name sounds a little different in Wales than it does in the United States.

The SSA ranks every spelling separately. Darrell and Darryl, or Dominic and its relatives, each get their own rank, so one sound can be more common than any single spelling suggests.

Unique, Rare and Strong Boy Names That Start With D

If you want unique boy names that start with D, look at old English surnames and place names. Behind the Name marks most of the names below as rare in English, yet every one of them is easy to read and say.

Name	Origin	Meaning
Dashiell	English (rare)	From the surname of author Dashiell Hammett’s mother, possibly an Anglicized form of French de Chiel, of unknown meaning
Dacre	English (rare)	From an English surname and Cumbrian place name of Brythonic origin: “trickling stream”
Denholm	English (rare)	From a surname and place name: “valley island” in Old English
Diggory	English (rare)	Probably an Anglicized form of Degaré, the hero of a medieval poem; may mean “lost one” from French égaré
Digby	English (rare)	From a surname and English town name: Old English “dyke, ditch” plus Old Norse “farm, town”
Drummond	English (rare)	From a Scottish surname based on place names, from Gaelic druim: “ridge”
Dunstan	English (rare), Anglo-Saxon	Old English dunn, “dark,” plus stan, “stone”; a 10th century saint and archbishop of Canterbury
Durward	English	From an English occupational surname: “door guard”
Darwin	English	From a surname derived from the Old English given name Deorwine; borne by the naturalist Charles Darwin
Devereux	English (rare)	From an English surname of Norman French origin: “from Evreux,” a town in France
Delano	English	From a surname meaning a person from La Noue (ultimately Gaulish “wetland, swamp”); used in honor of Franklin Delano Roosevelt

Unique and rare D names for boys.

Most of these began as last names that described a place or a family. Dacre, Denholm, Digby and Drummond are landscape names: a trickling stream, a valley island, a ditch and farm, and a ridge. Dunstan is older still, an Old English given name made of “dark” and “stone” and borne by a 10th century archbishop of Canterbury. Diggory has a story behind it, too: it probably comes from the hero of a medieval poem set in Brittany, and the reference says it may mean “lost one.”

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 D, meaning is the best guide. This letter has two dragons (Drake and Draco), a leader (Duke), a ruler of the world (Donald), a warrior of the people (Dieter), and iron (Demir). Our strong boy names list covers every letter.

Name	Origin	Meaning
Drake	English	From an English surname based on Old Norse Draki or Old English Draca: “dragon”
Duke	English	From the noble title, originally from Latin dux: “leader”
Donald	Scottish, English	From Scottish Gaelic Dòmhnall: “ruler of the world”; two 9th century kings of the Scots and Picts
Draco	Ancient Greek (Latinized)	From Greek Drakon: “dragon, serpent”; a 7th century BC Athenian legislator and a northern constellation
Dieter	German	Old German “people” plus “army”: “warrior of the people”; also a short form of Dietrich
Dalibor	Czech, Slovak, Croatian, Serbian, Slovene, Macedonian	Slavic “distance” plus “to fight”
Demir	Turkish, Bosnian	“Iron” in Turkish
Dejen	Amharic	“Foundation, support”

Strong and cool D names for boys.

Dalibor and Dejen show that strength does not have to sound harsh. Dalibor joins Slavic words for “distance” and “to fight,” while the Amharic name Dejen means “foundation, support,” a quieter kind of strength.

Short D Names for Boys (3 to 5 Letters)

Short D names are quick to write on a backpack tag, hard to shorten further and easy to pair with a long surname. Several began as nicknames and now stand on their own.

Name	Origin	Meaning
Dax	English	From an English surname, from the French town of Dax or the Old English name Dæcca (of unknown meaning)
Dex	English	Short form of Dexter
Don	English	Short form of Donald
Dash	English (modern)	Probably from the English word dash, “run, sprint”; sometimes a short form of Dashiell
Dirk	Dutch, Low German, German, English	Dutch and Low German short form of Diederik
Dion	Ancient Greek, English	From Greek Dios: “of Zeus”; a 4th century BC ruler of Syracuse
Doug	English	Short form of Douglas
Dev	Hindi, Marathi	From Sanskrit deva: “god”
Dane	English	From an English surname, either a variant of the surname Dean or a name for a person from Denmark
Dave	English	Short form of David
Danny	English, Dutch, German	Diminutive of Daniel

Short boy names starting with D.

Notice how many short D names are nicknames of longer D names: Dex from Dexter, Don from Donald, Doug from Douglas, Dave from David and Danny from Daniel. If you love the short form but want more options for a future grown man, you can put the long name on the birth certificate and use the short one every day.

Others are full names in their own right. Dev comes from the Sanskrit word for “god.” Dion comes from a Greek element meaning “of Zeus.” Dax has a double origin, either a French town or an Old English name of unknown meaning. More short names live in other tables: Dan and Dov (in the biblical and nature tables), Dag, Dai and Dino (in the international table), and Dale and Drew (in the gender neutral table).

Long, Elegant and Vintage D Names

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

Name	Origin	Meaning
Demetrius	Ancient Greek (Latinized)	Latinized form of Demetrios, derived from the name of the Greek goddess Demeter; several early saints
Dionysius	Ancient Greek (Latinized), biblical	Latin form of Dionysos; Dionysius the Areopagite is mentioned in the New Testament
Dorian	English, French, Romanian, Polish	First used by Oscar Wilde in The Picture of Dorian Gray (1891); he may have taken it from the ancient Greek tribe the Dorians
Decimus	Ancient Roman	Roman given name: “tenth” in Latin
Desiderius	Late Roman	From Latin desiderium: “longing, desire”; several early saints
Daxton	English (modern)	Elaboration of Dax influenced by names such as Paxton and Braxton

Long and elegant D boy names.

Demetrius and Dionysius are the two great Greek D names, and each one has spread into many languages. Demetrius gave Dmitri and Dimitar; Dionysius gave Denis and, through it, Dennis. Decimus is a plain Roman name that simply means “tenth,” and Desiderius, “longing, desire,” is the root of the French Didier.

These vintage picks feel familiar from parents’ and grandparents’ generations. Several are 20th century American favorites, and a few are pet forms that were given as full names.

Name	Origin	Meaning
Dennis	English, German, Dutch	Usual English, German and Dutch form of Denis
Douglas	Scottish, English	From a Scottish surname and town name: “dark river,” from Gaelic dubh, “dark,” and glais, “water, river”
Dudley	English	From a surname and place name: “Dudda’s clearing” in Old English

Darryl	English, African American	Variant of Darrell
Doyle	English	From an Irish surname, an Anglicized form of Ó Dubhghaill

Davey	English	Diminutive of David
DeAndre	African American	Combination of the name prefix de and Andre
Deshawn	African American	Combination of the name prefix de and Shawn; also spelled DeShawn

Vintage and old-fashioned D names for boys.

Behind the Name lists Darrell, Darryl and Darnell as both English and African American names. DeAndre and Deshawn are built the same way, from the popular name prefix de plus a familiar name.

Nature D Names: Valleys, Trees and Animals

These names connect to the natural world through their stated meaning: valleys, a palm tree, a sparrow, a bear, a pond, a forest, a mountaintop and a kind of grass. Dale, Dallas and Deniz (“sea” in Turkish) 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
Dalton	English	From an English surname and place name: “valley town” in Old English
Denton	English	From a surname and place name: “valley town” in Old English
Dekel	Hebrew	“Palm tree”
Dror	Hebrew	“Freedom” or “sparrow”
Dov	Hebrew	“Bear”
Delmar	English	From an English surname, from Norman French de la mare: “from the pond”
Deforest	English	From a French surname: “from the forest”
Doruk	Turkish	“Mountaintop”
Darnell	English, African American	From an English surname derived from Old French darnel, a type of grass; sometimes from a place name: “hidden nook”

Nature inspired D names for boys.

The Hebrew names are especially simple: Dekel means “palm tree,” Dov means “bear,” and Dror means “freedom” or “sparrow.” The English ones are mostly old place names, which is why Dalton and Denton share the exact same meaning, “valley town.” Douglas, in the vintage table, is another landscape name: “dark river.”

Mythology, Literature and Biblical D Names

Greek, Irish and Welsh stories all supply D names, and so does a classic French novel. Where the reference calls a meaning uncertain or unknown, as it does for Dionysus and for the root of Diarmuid, we print it that way.

Name	Origin	Meaning
Daedalus	Greek mythology (Latinized)	From Greek daidallo: “to work cunningly”; the inventor who designed the Labyrinth on Crete
Diomedes	Greek mythology	Greek “of Zeus” plus “plans, counsel, cunning”; one of the greatest heroes of the Trojan War
Dionysus	Greek mythology (Latinized)	Latin form of Dionysos; the meaning is uncertain, possibly related to Greek “of Zeus”
Deucalion	Greek mythology (Latinized)	Possibly related to Greek deuo: “to drench, to wet”; with his wife Pyrrha he survived a great flood
Damocles	Greek mythology (Latinized)	Greek damos, “the people,” plus kleos, “glory”
Dagda	Irish mythology	“The good god” in Old Irish; a leader of the Tuatha Dé Danann
Diarmuid	Irish, Irish mythology	Variant of Diarmaid, whose meaning is unknown (it has been suggested to mean “without envy”); a warrior of Irish legend
Dáire	Irish, Irish mythology	“Fruitful, fertile” in Irish; borne by many figures in Irish legend
Drystan	Welsh	Welsh form of Tristan
D’Artagnan	Literature	“From Artagnan,” a town in southwestern France; the aspiring musketeer in Alexandre Dumas’s The Three Musketeers

D names from mythology, legend and literature.

Daedalus is the inventor of Greek myth who designed the Labyrinth, and Diomedes is one of the great heroes of the Trojan War. On the Irish side, the Dagda is a leader of the Tuatha Dé Danann, Dáire is borne by many figures in Irish legend, and Diarmuid is a warrior of the old stories. Drystan is the Welsh form of Tristan, the hero of the medieval Tristan tales. Dylan, in the first table, is a figure of Welsh mythology as well.

For biblical boy names that start with D, the best known are Daniel and David from the first table. Per Behind the Name, Daniel was a Hebrew prophet whose story is told in the Book of Daniel, and David was the second king of Israel, ruling in the 10th century BC. Darius is also a biblical name: three ancient Persian kings bore it. Dionysius the Areopagite, in the long names table, is mentioned in the New Testament. Less common choices:

Dmitri and Dimitar come from Demetrius. Behind the Name also notes that Saint Dewi, the patron saint of Wales, was a 6th century bishop. For more Gaelic choices, see our Irish boy names list.

Dakarai	Shona	“Rejoice”

Arabic, Amharic, South Asian, East Asian and African D names.

Japanese and Korean names depend on the characters chosen. Daichi, Daisuke, Dong-hyun and Do-yun each have one common reading in the table, but the reference notes that other kanji or hanja combinations are possible, so the meaning a family intends can differ. Dumisani (“praise”) and Dakarai (“rejoice”) are complete, joyful words in Zulu, Ndebele and Shona.

Print accents and special letters exactly as the name is spelled: Dieudonné, Deaglán, Dáire, Dragoș and Dušan. 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 D Names

Behind the Name lists each of these as both masculine and feminine. Many began as English surnames or place names. You will find more in our gender neutral names guide.

Name	Origin	Meaning
Drew	English	Short form of Andrew, sometimes a feminine form; in the medieval period a form of Drogo
Devin	English	From a surname, either Irish or English
Devon	English, African American (modern)	Variant of Devin, possibly also inspired by the county of Devon in England

Darian	English	Probably an elaborated form of Darren
Dusty	English	From a nickname, and a diminutive of Dustin
Dayo	Yoruba	“Joy arrives”
Deniz	Turkish	“Sea”

Gender neutral names that start with D.

Drew is a nice example of a name with two histories: the reference calls it a short form of Andrew, and also a medieval vernacular form of the Frankish name Drogo. Dayo, from Yoruba, has one of the warmest meanings on this page: “joy arrives.”

Why D Names Are Loved: Sound, Spelling and Nicknames

D gives a name a firm, friendly start. A few plain reasons parents keep coming back to this letter:

The sound is clear and solid, and it works with almost any vowel: Dax, Dean, Dion, Doug, Duke.
The range is wide: one syllable (Dean, Drake, Duke) to four or more (Demetrius, Dionysius, Diomedes), ancient (Darius, Decimus) to modern (Daxton, Dash).
The meanings are appealing. Dragons (Drake, Draco), “beloved” (David), “of the Lord” (Dominic), “given” (Donato) and “given by God” (Dieudonné) all sit under this letter.
The big D names travel well. David, Daniel, Dominic and Demetrius each have a matching form in many languages.

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

The David family: David, Dave, Davey, Davis, Dawson, Davi, Davide, Dafydd, Dai, Dewi, Dawid, Dawud and Dawit.
The Daniel family: Daniel and Danny.
The Dominic family: Dominic, Domingo, Domenico and Dominik.
The Demetrius family: Demetrius, Dmitri and Dimitar.
The Dionysius family: Dionysius, Denis and Dennis, plus Dionysus from Greek myth.
The Theodoric family: Derek, Dietrich, Diederik and Dirk all trace back to Theodoric, “ruler of the people.”

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 David could inspire a Dafydd or a Davis; a great-uncle Dennis could become a Denis.

Full name	Nickname ideas
Daniel	Danny
David	Dave, Davey (and the Welsh Dai, a diminutive of Dafydd)
Donald	Don, Donnie
Douglas	Doug
Dexter	Dex
Dashiell	Dash (the reference says Dash is sometimes a short form of Dashiell)
Dustin	Dusty
Dieter	Dieter itself is also used as a short form of Dietrich

Nickname ideas for D 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:

Daniel and Declan
David and Dashiell
Dylan and Desmond
Dominic and Duke
Diego and Dario
Dexter and Dawson
Darius and Dorian
Dov and Dror
Dafydd and Dewi
Daichi and Daisuke

You can also link siblings through meaning instead of sound. Drake and Draco both mean “dragon.” Dalton and Denton both mean “valley town.” Dekel and Deforest both point to trees, and Dag and Dinesh both carry the word for “day.”

For a sister, the unisex picks Darcy, Dallas, Dakota and Dale keep the letter, or you can match from girl names that start with B. For a brother with a different initial, try boy names that start with C.

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: Dean Theodore, Dax William, Dominic James, Declan Henry, Desmond Oliver and Dylan James. D names also make easy middle names themselves: Dean, Drew, David, Daniel and Dale all sit comfortably in the second slot. Our middle names guide has more.

The Initials Check and Other Quick Tests

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

Initials: write out first, middle and last initials. D.A.N. and D.E.W. are charming. D.U.D. and D.I.E. 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 a D or T sound (David, Desmond, Dwight) can blur into a surname that starts with D, so listen for the break.
Spelling: if there are several spellings (Darrell and Darryl, Devin and Devon, Duane and Dwayne, Dmitri and Dimitar), decide whether you mind correcting people.
Nicknames: check the nickname table above. If you dislike the obvious short form (Doug for Douglas, Don for Donald), 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 D covers nearly every style: timeless classics like Daniel and David, Irish favorites like Declan and Desmond, rare finds like Dashiell, Diggory and Dunstan, and names from Hebrew, Welsh, Turkish, Amharic, Sanskrit, Japanese, Korean, Zulu and Shona. 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.
