Looking for unique boy names that do not sound made up? This guide groups rare, cool and uncommon choices, with an origin or meaning where it is well documented. It also shows you how to check any name on the Social Security Administration site, and how to test its spelling and pronunciation.
Few children around your son share it. No list can promise that, so treat “unique” as a guide. Check your favorites on the Social Security Administration site before you decide.

Name meaning
This is not a ranking. None of the names in our tables appear in the SSA top 200 boy names for 2020 to 2025. That is the only popularity check we make. A name can be outside that list and still be common in your town. Origins and meanings in every table on this page come from Behind the Name. Where that source hedges, the table hedges too.
Rare boy names here means names most people do not meet every day. Many searches ask for very rare unique boy names, but no list can promise that no one else has a name. Treat these as starting points, then run the checks further down.
| Name | Origin or meaning |
|---|---|
| Fintan | Possibly from Irish words for “white fire” or “white ancient” |
| Tiernan | Anglicized form of the Irish name Tighearnán |
| Osric | Old English elements for “god” and “ruler, king” |
| Emrys | Welsh form of Ambrose |
| Cillian | Probably from Old Irish for “church,” with a diminutive ending |
| Thaddeus | Greek form of an Aramaic name. Possibly from a word for “heart, breast” |
If the story behind a name matters most, start here. These unique boy names with meaning have a clear origin in our source. Each one gives you something to tell your son when he asks why you chose it.
| Name | Origin or meaning |
|---|---|
| Peregrine | From Latin Peregrinus, “traveler” |
| Alaric | Gothic, “ruler of all” |
| Rafferty | From an Irish surname, based on Rabhartach, “flood tide” |
| Anselm | Old German elements for “god” and “helmet, protection” |
| Cyprian | From Latin Cyprianus, “from Cyprus” |
| Ambrose | From Greek Ambrosios, by way of Late Latin, and linked to a word for immortality |
| Casimir | English form of Polish Kazimierz, from Slavic words for “destroy” and “peace, world” |
Cool boy names are a matter of taste, so this group is our editorial pick. These have a strong sound or a link to the sky, the Bible or the ancient world. Check the meanings too, because several are uncertain.
| Name | Origin or meaning |
|---|---|
| Cassius | Probably a Roman family name, perhaps from Latin cassus, “empty, vain” |
| Orion | From Greek mythology. The meaning is uncertain, possibly linked to a word for “boundary” |
| Stellan | Swedish. The meaning is unclear, possibly from an Old Norse word for “calm” |
| Jericho | From a city in the Old Testament. The meaning is uncertain |
| Rhys | Probably from Old Welsh Ris, possibly “passion, eagerness” |
Unique baby boy names do not need to be hard work. These are simple in English, so they are less likely to need spelling out. All of them are still outside the SSA top 200 we checked.
| Name | Origin or meaning |
|---|---|
| Bram | Short form of Abraham |
| Ansel | English surname taken from the given name Anselm |
| Otis | English surname from the medieval name Ode, a relative of Otto |
| Linus | From Greek Linos, from a word for “flax” |
| Anders | Scandinavian form of Andreas |
| Soren | Anglicized form of the Danish name Søren |
| Barnaby | English form of Barnabas |
Uncommon boy names often come from books and legends. These four appear in myth, medieval poetry or ancient history. Read the story first, since a name carries its character with it.
| Name | Origin or meaning |
|---|---|
| Percival | Coined by the French poet Chrétien de Troyes. It may come from Old French for “pierce the valley” |
| Auberon | Diminutive of Auberi, an Old French form of Alberich. It is the fairy king in a medieval French epic |
| Ulysses | Latin form of Odysseus |
| Lysander | Latinized form of Greek Lysandros, from words for “release, loosening” and “man” |
Unusual boy names can feel new to your friends and still be very old. Some of these come from outside English, so learn how the name is used and said in its home culture before you commit.
| Name | Origin or meaning |
|---|---|
| Ignatius | From the Roman family name Egnatius, meaning unknown. The spelling was later shaped by Latin ignis, “fire” |
| Lazarus | Latinized form of Greek Lazaros, a form of Eleazar. It appears in the New Testament |
| Aurelius | Roman family name, reportedly from Latin aureus, “golden” |
| Kenzo | Japanese. The meaning depends on the kanji, such as a character for “modest,” “healthy” or “wise” plus one for “three” |
| Idris | Arabic, possibly “interpreter” or “teacher.” It is also a separate Welsh name |
| If you want | Start with | Names to try |
|---|---|---|
| A name few people meet every day | Rare boy names | Fintan, Tiernan, Osric |
| A clear story behind the name | Unique boy names with meaning | Peregrine, Alaric, Rafferty |
| A bold sound | Cool boy names | Cassius, Orion, Stellan |
| A name that is easy to say | Unique baby boy names | Bram, Otis, Linus |
| A link to books and legends | Uncommon boy names from old stories | Percival, Ulysses, Lysander |
| An old name that feels new | Unusual boy names | Ignatius, Aurelius, Kenzo |
Check the meaning yourself: Name meanings are often debated, and some are simply unknown. Orion and Stellan are two examples on this page. Look up the name in a reliable reference before you order anything engraved.
A name that feels rare to you may not be rare where you live. These checks take a few minutes. They use public data and a little common sense.
A name that looks unique on paper can trip people up out loud. Some of these sounds do not match English spelling rules. The guides below are our plain-English versions of the pronunciations on Behind the Name.
| Name | How to say it in English | Watch for |
|---|---|---|
| Rhys | REES | Sounds like Reese, so look up both spellings at SSA |
| Seamus | SHAY-mus | Irish form of James. The “Sea” sounds like “shay” |
| Cassius | KASH-us or KASS-ee-us | Both are listed, so pick one and use it every time |
| Ulysses | yoo-LISS-eez | American and British stress can differ |
| Emrys | EM-riss | The “y” sounds like a short “i” |
| Auberon | AW-buh-ron or OH-buh-ron | Both are listed, so pick one and use it every time |
Pick a spelling and stick to it on every form. For a hospital or birth certificate form, write the name in block capitals and check it before you sign. A short note on your birth announcement can also teach the pronunciation early.

No. The groups are our editorial choices, not rankings. We only checked that each name is outside the SSA top 200 boy names for 2020 to 2025.
No one can say for sure, because SSA leaves out names with fewer than 5 occurrences in any geographic area. Start with the rare names above, then look up your favorites on the SSA site.
Use the Popularity of a Name tool on the SSA baby names site. Check every likely spelling, because SSA counts each spelling separately. Then ask around your own community.
Bram, Otis, Linus and Anders are short and follow common English spelling. Say each one out loud and spell it for a friend to test it.
From Behind the Name, a reference site on name origins. Some meanings are uncertain, and our tables say so when the source does.
