Boy names that start with S run from classics like Samuel and Sebastian to rare finds like Sholto and Somerled, and this list of 119 gives a checked origin and meaning for every one.
S is a generous letter for naming a son. It holds timeless classics like Samuel, Simon and Stephen, Norse and Roman legends, English surname names like Spencer and Sullivan, and names from languages around the world. And since no S name is in the boys’ 2025 top 10 from the Social Security Administration, even the familiar ones feel a little less crowded.
We grouped these boy names that start with S by style: familiar, unique, strong, short, long and 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 S name is in the boys’ 2025 top 10 from the Social Security Administration.

Boy Names That Start With S at a Glance
Quick Answer
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 or only possible, we say so.
How to read the tables: the Origin column uses the reference’s own usage labels, so “English (modern)” or “Old Norse (Anglicized)” is its wording, 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 usually sits elsewhere on this page with its own meaning.

| Name | Origin | Meaning |
|---|---|---|
| Samuel | English, French, German, Spanish, Scandinavian, Jewish, biblical and more | From Hebrew Shemuel, usually read as “name of God,” or possibly “God has heard”; the prophet who anointed Saul and David |
| Sebastian | German, English, Scandinavian, Polish, Czech and more | From Latin Sebastianus, “from Sebaste,” a city named from the Greek sebastos, “venerable”; Saint Sebastian was a 3rd century Roman soldier |
| Silas | English, Greek, Danish, German, biblical | Probably a short form of Silvanus; a companion of Saint Paul in the New Testament |
| Santiago | Spanish, Portuguese | Spanish “saint” plus Yago, an old Spanish form of James, so roughly “Saint James,” after Spain’s patron saint |
| Simon | English, French, German, Scandinavian, Dutch, Hungarian, biblical and more | New Testament Greek form of the Hebrew Shimon, “hearing, listening”; the name of the apostle also called Peter |
| Stephen | English, biblical | From the Greek Stephanos, “crown, wreath”; Saint Stephen is regarded as the first Christian martyr |
| Steven | English, Dutch | Medieval English form of Stephen and Dutch form of Stefan |
| Spencer | English | From an English surname for someone who handed out supplies, from Middle English spense, “larder, pantry” |
| Solomon | Biblical, English, Jewish | From Hebrew Shelomo, linked to shalom, “peace”; the wise king of Israel, son of David and Bathsheba |
| Seth | English, biblical | From Hebrew: “placed, set”; the third son of Adam and Eve in the Old Testament |
| Scott | English, Scottish | From a surname for a person from Scotland or a speaker of Scottish Gaelic, from the Latin Scoti |
| Sean | Irish, English | Anglicized form of Seán, the Irish form of John |
| Shane | Irish, English | Anglicized form of Seán; it spread in America after the 1953 western movie Shane |
| Sterling | English | From a Scottish surname based on the town of Stirling (meaning unknown), or from the word sterling, “excellent” |
Here is the one popularity fact worth knowing: no S name is in the boys’ 2025 top 10 from the Social Security Administration (SSA). That surprises many parents, because S names are everywhere on playgrounds. It also means a familiar S name like Samuel or Sebastian feels well known without being the name of three boys in the same class.
A few notes on the table. Sean and Shane are both Anglicized forms of the Irish Seán, which is itself the Irish form of John, so they are cousins of one of the oldest names in English. Stephen and Steven are one name in two spellings, and Behind the Name calls Steven the medieval English form. Silas, a companion of Saint Paul, is probably a short form of Silvanus, a Roman name meaning “of the woods” that appears later on this page.
Several familiar S names sit in the gender neutral table further down, including Sawyer, Sidney and Sage, because the reference lists them for both boys and girls. Each name appears in only one table on this page.
Unique, Rare and Strong Boy Names That Start With S
If you want unique boy names that start with S, start here. None of these is common in the United States, and the reference marks a couple of them as rare even in English, yet every one is easy to read.
| Name | Origin | Meaning |
|---|---|---|
| Sholto | Scottish | Probably an Anglicized form of the Gaelic sìoltaich, “sower, propagator”; used now and then in the Douglas family since the 17th century |
| Somerled | Old Norse (Anglicized) | Anglicized form of the Old Norse Sumarliði, roughly “summer traveler”; a 12th century king of Mann and the Scottish Isles |
| Sorley | Scottish | Anglicized form of Somhairle, the Scottish Gaelic form of Somerled |
| Selwyn | English (rare) | From a surname based on an Old English given name: sele, “manor,” plus wine, “friend” |
| Saxon | English (rare) | From a surname based on the Saxons, a Germanic tribe whose name traces to a word for “knife” |
| Stellan | Swedish | Meaning unknown; perhaps related to the Old Norse stilling, “calm,” or perhaps of German origin |
| Severin | German; Scandinavian (rare) | German and Scandinavian form of Severinus, a Roman name formed from Severus |
| Soren | English (modern) | English form of Søren |
| Septimus | Ancient Roman | A Roman given name meaning “seventh” in Latin |
| Sixtus | Late Roman | Probably the Latin form of the Greek Xystos, possibly “scraped, polished,” or from Latin for “sixth”; borne by five popes |
Scotland supplies three of the best. Sholto is probably from a Gaelic word for “sower,” and Somerled, Sorley and the Gaelic Somhairle all trace to one Old Norse name meaning roughly “summer traveler.” Stellan is the honest exception: Behind the Name says its meaning is unknown and offers only possibilities, so we print it that way. Septimus and Sixtus are old Roman names built on numbers, seventh and possibly sixth, which makes them a quiet nod for a family where birth order matters.

For strong or cool boy names that start with S, look at meaning rather than sound. Sigmund joins “victory” and “protection,” Severus means “stern,” Snorri means “attack, onslaught,” and Simba means “lion” in Swahili. Sanjay and Suresh come from Sanskrit names meaning “completely victorious” and “ruler of the gods.” Our same-day list of strong boy names has many more.
| Name | Origin | Meaning |
|---|---|---|
| Sigmund | German, Norwegian, English, Norse mythology | Old German and Old Norse words for “victory” and “protection”; the father of the hero Sigurd in the Völsungasaga |
| Severus | Ancient Roman | A Roman cognomen meaning “stern” in Latin |
| Snorri | Old Norse, Icelandic | From the Old Norse snerra, “attack, onslaught”; borne by the 13th century Icelandic writer Snorri Sturluson |
| Sixten | Swedish | From the Old Norse Sigsteinn: sigr, “victory,” plus steinn, “stone” |
| Simba | Swahili | “Lion” in Swahili; the lion cub hero of The Lion King (1994) |
| Sanjay | Hindi, Marathi, Bengali, Tamil, Telugu and more | Modern form of Sanjaya, Sanskrit for “completely victorious, triumphant” |
| Suresh | Hindi, Marathi, Tamil, Telugu, Malayalam, Kannada, Nepali | Modern form of Suresha, Sanskrit for “ruler of the gods” |
Short S Names for Boys (3 to 4 Letters)
Short S names are quick to write on a cubby label and sit well beside a long surname. Most of them began as short forms of longer names, so they also work as everyday nicknames for a formal first name.
| Name | Origin | Meaning |
|---|---|---|
| Sid | English | Short form of Sidney |
| Stan | English | Short form of Stanley; borne by the comedian Stan Laurel |
| Stu | English | Short form of Stuart |
| Steve | English, French | Short form of Steven |
| Sol | Jewish | Short form of Solomon |
| Sven | Swedish, Norwegian, Danish, German, Dutch, Estonian | From the Old Norse byname Sveinn, “boy”; borne by kings of Denmark, Norway and Sweden |
| Stig | Swedish, Norwegian, Danish | Modern form of Stigr |
Two of these stand on their own feet. Sven comes from an Old Norse byname that simply means “boy,” and it was borne by kings of Denmark, Norway and Sweden. Stig is listed only as a modern form of the Old Norse Stigr, with no meaning given, so we leave it there. The rest, from Sid to Sol, are short forms whose full names appear elsewhere on this page.
More short S names live under other headings: Sam, Sal, Sky and Shai have three or four letters and sit in the gender neutral table, and Seth, Sean, Saul, Sten, Said and Sami have four.
Long, Elegant and Vintage S Names
Many long S names for boys began as English surnames, and most of them describe a job or a place. That gives them a solid, grown-up feel, and several come with a ready nickname for the toddler years.
| Name | Origin | Meaning |
|---|---|---|
| Stanley | English | From an English surname meaning “stone clearing,” from Old English stan, “stone,” and leah, “woodland, clearing” |
| Stuart | English, Scottish | From a Scottish surname for a steward, from Old English words for “house” and “guard”; honors the royal house of Stuart |
| Stewart | English, Scottish | From a surname that was a variant of Stuart |
| Sullivan | English, French | From the Irish surname Ó Súileabháin, based on súil, “eye,” and dubh, “dark, black” |
| Sheldon | English | From a surname taken from an Old English place name, “valley with steep sides” |
| Seymour | English | From a Norman surname for someone from Saint-Maur in France, “Saint Maurus” |
| Sherman | English | From an English surname for a “shear man,” a person who cut cloth |
| Sanford | English | From a surname and place name meaning “sand ford” in Old English |
| Sampson | English | From an English surname taken from a medieval form of Samson |
Read the meanings and you can almost see medieval England: a stone clearing (Stanley), a steward running a household (Stuart), a man who cut cloth (Sherman), a sandy river crossing (Sanford) and a steep-sided valley (Sheldon). Stuart and Stewart are one name in two spellings, and Behind the Name ties the given name to the royal house of Stuart. Sullivan is the Irish link in the group, from a surname built on words for “eye” and “dark.”

Nature S Names: Stone, Forest, Sea and Sun
These names connect to the natural world through their stated meaning: stone, forest, sea, sun, shore and even “red water.” A name earns a place here only if its entry ties it to nature, not because it sounds outdoorsy.
| Name | Origin | Meaning |
|---|---|---|
| Sten | Swedish, Danish, Norwegian, Estonian | From the Old Norse name Steinn, “stone” |
| Sylvester | English, German, Danish | Medieval variant of Silvester, from Latin silva, “forest”; now the usual English spelling |
| Silvio | Italian, Spanish | Italian and Spanish form of Silvius, from Latin silva, “forest, wood” |
| Silvano | Italian | Italian form of Silvanus, “of the woods” |
| Sagar | Hindi, Marathi, Bengali, Gujarati, Odia, Punjabi | Modern form of Sagara, Sanskrit for “sea, ocean” |
| Surya | Hinduism, Hindi, Tamil, Telugu, Indonesian and more | Sanskrit: “sun”; the Hindu god of the sun, who rides a chariot across the sky |
| Sahil | Azerbaijani, Hindi, Urdu | “Coast, shore,” borrowed in all three languages from Arabic |
| Sohrab | Persian, Persian mythology | From Persian sohr, “red,” and ab, “water”; the son of the hero Rostam in the Shahnameh |
The Latin word silva, “forest,” runs through a whole family of S names. Sylvester and Silvio come straight from it, Silvano is the Italian form of Silvanus, and Silvanus, “of the woods,” is in the mythology table below. Silas may belong to the same family, since Behind the Name calls it probably a short form of Silvanus.
More nature names sit in the gender neutral table because the reference lists them for both boys and girls: Sky (from an Old Norse word for “cloud”), Sora (Japanese for “sky”), Storm, Sunny and Sage, the herb. Stanley (“stone clearing”) and Sanford (“sand ford”) also read like a line from an old map.
Mythology, Literature and Biblical S Names
Norse sagas, German legend, Roman gods, Persian epic and a hobbit all supply S names. Where the reference only gives a possible origin, or none, as with Saturn, we say so.
| Name | Origin | Meaning |
|---|---|---|
| Sigurd | Norwegian, Danish, Swedish, Norse mythology | From the Old Norse Sigurðr: “victory” plus “guard, guardian”; the dragon-slaying hero of the Völsungasaga |
| Siegfried | German, Germanic mythology | Old German words for “victory” and “peace”; the hero of the Nibelungenlied |
| Sindri | Norse mythology, Old Norse, Icelandic | From Old Norse, linked to “sparkling”; the dwarf who helped make Thor’s hammer |
| Saturn | Roman mythology (Anglicized) | From Latin Saturnus, of unknown meaning; the Roman god of agriculture and the ringed sixth planet |
| Silvanus | Roman mythology, Ancient Roman, biblical | A Roman cognomen meaning “of the woods”; the Roman god of forests, and the fuller name of Saint Paul’s companion Silas |
| Siavash | Persian, Persian mythology | Persian form of the Avestan Siiāuuaršan, “possessing black stallions”; a virtuous prince of Iranian legend |
| Samwise | Literature | Old English elements for “half” and “wise,” read as “simple, half wise”; Frodo’s loyal companion in The Lord of the Rings (1954) |
| Socrates | Ancient Greek (Latinized) | From the Greek sos, “safe, unharmed,” and kratos, “power”; the Athenian philosopher known through his student Plato |
Sigurd and Siegfried are two versions of one hero. Behind the Name notes that the stories of the German Siegfried were partly based on the Norse Sigurd, who kills the dragon Fafnir. Sigmund, Sigurd’s father in the saga, is in the strong names table above. Samwise is a sweet literary pick: Tolkien built it from Old English words for “half” and “wise,” and the character goes by Sam.
For biblical boy names that start with S, the best known are Samuel, Simon, Stephen, Solomon, Seth and Silas from the first table. Simeon is the Old Testament spelling of the name that became Simon, and the Hebrew Shimon covers both. Less common choices with Bible roots:
| Name | Origin | Meaning |
|---|---|---|
| Saul | Biblical, Jewish | From Hebrew Shaul, “asked for, prayed for”; the first king of Israel, and the Hebrew name of the apostle Paul |
| Shadrach | Biblical | Akkadian, usually read as “command of Aku,” the Babylonian moon god; one of the three men saved from the fiery furnace |
| Sergius | Ancient Roman, biblical | A Roman family name, possibly “servant,” though the origin is most likely unknown; a Roman official in the New Testament |
| Salomon | French, biblical | French and Polish form of Solomon, also the Greek and Latin Old Testament form |
Saul is a striking case: the same Hebrew name belonged to Israel’s first king and was the original name of the apostle Paul. Our full list of biblical boy names goes well beyond the letter S.
International S Names by Language
The origin labels below are the reference’s own usage labels. Where an entry says only that a name is the form of another name in a given language, we print exactly that and point you to the root name on this page.
| Name | Origin | Meaning |
|---|---|---|
| Sergio | Italian, Spanish | Italian and Spanish form of Sergius |
| Stefano | Italian | Italian form of Stephen |
| Sebastiano | Italian | Italian form of Sebastianus (see Sebastian) |
| Salvatore | Italian | Italian counterpart of Salvador |
| Saverio | Italian | Italian form of Xavier |
| Santino | Italian | Diminutive of Santo, Italian for “saint” |
| Salvador | Spanish, Portuguese, Catalan | From the Late Latin Salvator, “savior,” referring to Jesus; borne by the painter Salvador Dalí |
| Simón | Spanish | Spanish form of Simon; borne by the South American revolutionary Simón Bolívar |
| Sébastien | French | French form of Sebastianus (see Sebastian) |
| Seán | Irish | Irish form of John, through the Old French Jehan |
| Somhairle | Scottish Gaelic | Scottish Gaelic form of the Old Norse Sumarliði (see Somerled) |
| Stefan | German, Scandinavian, Dutch, Polish, Bulgarian, Serbian, Macedonian | Form of Stephen; three Serbian rulers of this name are Orthodox saints |
| Sander | Dutch, Estonian, Danish, Norwegian | Short form of Alexander |
| Snorre | Norwegian | Norwegian form of Snorri |
| Sindre | Norwegian | Norwegian form of Sindri |
| Sakari | Finnish | Finnish form of Zacharias |
| Szymon | Polish | Polish form of Simon |
| Stanislav | Czech, Slovak, Russian, Ukrainian, Bulgarian, Serbian, Croatian, Slovene | Slavic stati, “stand, become,” plus slava, “glory”; a medieval bishop of Kraków bore the Polish form |
| Sergei | Russian, Bulgarian | Alternate transcription of Sergey, the Russian and Bulgarian name |
| Sándor | Hungarian | Hungarian form of Alexander |
| Sotiris | Greek | Variant of Sotirios, the modern Greek form of Soterios, from soter, “savior, deliverer” |
| Spyridon | Greek, Late Greek | From the Greek spyridion, “basket,” or the Latin spiritus, “spirit”; a 4th century shepherd who became a bishop |
A handful of root names do most of the work. Stefano and Stefan are forms of Stephen. Simón and Szymon are forms of Simon. Sergio and Sergei connect to the Roman Sergius, Sebastiano and Sébastien to Sebastian, and Sander and Sándor are short and Hungarian forms of Alexander. Snorre and Sindre are the Norwegian forms of the Old Norse Snorri and Sindri found elsewhere on this page.
| Name | Origin | Meaning |
|---|---|---|
| Shlomo | Hebrew | Modern Hebrew form of Solomon |
| Shimon | Hebrew, biblical Hebrew | Hebrew form of Simeon and Simon |
| Sulayman | Arabic, Kyrgyz, Uyghur, Quranic | Arabic form of Solomon; it appears in the Quran |
| Salim | Arabic, Urdu | Arabic: “safe, sound, intact,” from salima, “to be safe” |
| Samir | Arabic, Azerbaijani | Arabic: “companion in evening talk,” from samara, “to talk in the evening” |
| Said | Arabic, Uzbek, Tajik, Indonesian, Malay and more | Arabic: “happy, lucky”; borne by a companion of the Prophet Muhammad |
| Sami | Arabic, Turkish, Albanian | Arabic: “elevated, lofty, supreme,” from sama, “to be high” |

| Shankar | Hindi, Marathi, Bengali, Tamil, Telugu and more | Modern transcription of Shankara: Sanskrit for “favorable, fortunate” plus “maker, doer”; another name of Shiva |
| Sipho | Zulu, Xhosa, Ndebele | From isipho, “gift” |
| Sizwe | Xhosa | “Nation,” from isizwe |
| Satoru | Japanese | Written with characters meaning “enlightenment” or “intelligent, clever”; other characters are possible |
Solomon may be the most widely traveled S name of all: on this page alone it appears as Solomon, Salomon, Shlomo, Sulayman and Sol. If a name comes from a faith or culture outside your own family, take a little time to learn how it is used and said. Some carry deep religious meaning; Behind the Name notes, for example, that Shankara is another name for Shiva and that Siddhartha was the Buddha’s birth name.
Print accents exactly as the name is spelled: Seán, Simón, Sébastien and Sándor. U.S. paperwork does not always carry accents, so decide ahead of time whether you are comfortable seeing the name without its mark on some documents. The reference gives pronunciations for many entries, for example /san.ˈtja.ɣo/ for Spanish Santiago, /se.bas.tjɛ̃/ for French Sébastien and /ˈʃaːn.dor/ for Hungarian Sándor.
Gender Neutral S Names
Behind the Name lists each of these names as both masculine and feminine. Several are English words or surnames, and a few come from Hebrew, Japanese, Russian and Arabic. The reference notes that Sidney was traditionally a boy’s name but was given more often to American girls from 1993 to 2019, and that Sultan is usually masculine in the Arab world but used for both in Turkey. More ideas: our gender neutral names guide.

Why S Names Are Loved, Plus Nicknames
A few plain reasons parents keep coming back to this letter:
- S is a soft sound that blends easily into other consonants (St, Sh, Sk, Sl), which gives the letter more variety than most.
- The range is wide: one syllable (Sven, Scott, Stig) to four (Sebastian, Siddharth), ancient (Septimus, Severus) to modern (Sawyer, Sutton).
- The meanings are appealing: “peace” (Solomon), “gift” (Sipho, possibly Shai), “sun” (Surya), “happy, lucky” (Said) and “stone” (Sten).
- The big S names travel well. Samuel, Simon, Stephen and Sebastian each have a matching form in many languages.
That last point is easier to see as families. Each line groups names that the reference links to one another:
- The Stephen family: Stephen, Steven, Stefan, Stefano and Steve.
- The Simon family: Simon, Simón, Szymon and Shimon.
- The Solomon family: Solomon, Salomon, Shlomo, Sulayman and Sol.
- The Sebastian family: Sebastian, Sebastiano and Sébastien.
- The forest family: Silvanus, Silas, Silvano, Silvio and Sylvester.
- The Seán family: Seán, Sean and Shane.
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.
| Full name | Nickname ideas |
|---|---|
| Samuel | Sam, Sammy, Sammie (Samu in Spanish; Sami, Samppa, Samu in Finnish) |
| Stephen, Steven | Steve, Stevie, Steph, Ste (Steve is a short form of Steven) |
| Sebastian | Bastian (German); Seppo, Sepi (Finnish) |
| Solomon | Sol, Solly (Jewish) |
| Stanley | Stan |
| Stuart | Stu |
| Sidney | Sid |
| Sylvester | Sly; Vester (Danish) |
| Samwise | Sam |
| Spyridon | Spiro, Spiros, Spyro, Spyros (Greek) |
| Stanislav | Slava, Stas (Russian, Ukrainian); Slávek (Czech); Stane, Staš (Slovene) |
| Simon | Siem (Dutch), Sime (Macedonian) |
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:
- Samuel and Silas
- Sebastian and Sven
- Santiago and Simón
- Stellan and Sigurd
- Solomon and Saul
- Spencer and Stuart
- Sholto and Somerled
- Salim and Samir
- Sipho and Sizwe
- Sagar and Surya
You can also link brothers through meaning instead of sound. Sylvester and Silvio both come from the Latin word for forest. Sagar (“sea”) and Sahil (“shore”) make a natural pair, and Sigmund, Sigurd and Sixten all begin with an element meaning “victory.” Our twin names guide has more pairing ideas.
For a sister, the unisex picks Sage, Sutton and Salem keep the letter, or browse our girl names that start with S. For a brother with a different initial, try our boy names that start with A.
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. S names also make easy middle names themselves: Scott, Seth, Sven and Sten sit comfortably in the second slot, and so do longer classics like Stephen, Sullivan and Sebastian. Our middle names guide has more ideas.
The Initials Check and Other Quick Tests
Before you settle on boy names that start with S, run each finalist through four quick tests:
- Initials: write out first, middle and last initials. If a combination spells a word you would rather not see on a backpack, swap the middle name.
- Say it out loud: call the full name across a room. A first name that ends in S can blur into a surname that starts with S (Silas Smith), and a run of S sounds can be a mouthful.
- Spelling: if a name has close cousins (Stephen and Steven, Stuart and Stewart, Sean and Shawn), decide whether you mind correcting people.
- Nicknames: check the table above. If you dislike the obvious short form, such as Sly for Sylvester or Stu for Stuart, assume someone will use it anyway.
One last check: say the full name together with any brothers’ or sisters’ names. You will be calling them as a set for years, so make sure the combination feels easy on a busy morning.

The Bottom Line
The letter S covers nearly every style: steady classics like Samuel, Simon and Stephen, rare Scottish finds like Sholto and Somerled, Norse heroes like Sigurd, and names from Hebrew, Arabic, Sanskrit, Swahili, Zulu, Xhosa and Japanese. No S name is in the boys’ 2025 top 10, so even a familiar choice stands out a little. Shortlist three to five, check the meaning, test the initials and say each one out loud for a week.
Once the name is settled, sleep is usually the next big project, and Betteroo can help you build a calm routine from the first weeks.
