Unique boy names are trending now more than ever before. Today's unique names for boys range from new inventions to ancient treasures, from names that cross gender boundaries to names drawn from international cultures.
Fifty years ago, the Top 20 boys' names represented 41% of all male children. Now, the Top 20 boy names represent less than 15% of all baby boys, with many more boys given rare or unusual names. That means that unique and unusual boy names are more likely to be accepted at school or in the workplace.
Some of the coolest unique names for boys today are mythological names and names from ancient cultures, such as Caius and Lucius from Ancient Rome and Linus from Ancient Greece. The Bible is a rich source of unique boys' names, as are nature, word, and surname names.
What are the most unique boy names? That distinction has to go to names you invent yourself or names you fashion from a family surname, a meaningful place name, or a word with personal significance.
Boy names uncommon in your neighborhood may be very different from city to city, state to state, and of course country to country. For all the lists of popular and unique boy names around the world, go to the main Popular Names page.
Here is a selection of our favorite rare and unique names for boys, from Ozias to Ozni to Parable, ordered by their current popularity on Nameberry.

- Kit
Origin:
English, diminutive of ChristopherMeaning:
"bearer of Christ"Description:
Actor Kit Harington, aka the dreamy Jon Snow on Game of Thrones, has given this nickname-name new style and appeal for boys. Actress Jodie Foster used it for her son.
- Zephyr
Origin:
GreekMeaning:
"west wind"Description:
If you're looking for a name that's light and breezy, this could be it. A name from mythology: Zephyrus/Zephyr was the Greek god of the west wind-- with many European variations, it's a name that's frequently seen in computer and video games, is a character in the children's book Silverwing, and appears in the Babar books--as a monkey.
- Elio
Origin:
Italian, SpanishMeaning:
"sun"Description:
Elio is a sunny and spirited Italian and Spanish name that makes a great crossover prospect, which could catch on as Enzo has. Elio is also currently popular in France, ranking in the Top 250.
- Emrys
Origin:
Welsh, variation of AmbroseMeaning:
"immortal"Description:
If you're looking for a Welsh name less common than Dylan, Griffin, Evan, or Morgan, you might want to consider this offbeat epithet of the wise wizard Merlin.
Root name Ambrose is an ancient saints' name derived from the Greek ambrosia, the food and drink of the gods that conferred immortality.
- Aurelius
Origin:
LatinMeaning:
"the golden one"Description:
Since Aurelius was given the supermodel seal of approval by Elle Macpherson, it has joined Augustus as an ancient Roman name that feels usable today. Slightly mystical and magical, Aurelius is grounded by its similarity to rising stars Aurora, Aurelia, and Atticus, and its golden aura is certainly appealing.
- Lysander
Origin:
GreekMeaning:
"liberator"Description:
Lysander is a distinctive Greek name that could be thought of as a more creative cousin of Alexander. In ancient history, Lysander was the name of an esteemed Spartan naval commander and his literary cred comes from one of the two star-struck young men in Shakespeare's A Midsummer Night's Dream, as well as one of the twin sons (the other being Lorcan) of Luna Lovegood, whom we learn about in the Harry Potter epilogue.
- Ozias
Origin:
Greek, HebrewMeaning:
"my strength is God"Description:
A cool Biblical option that currently sits just outside the US Top 1000, Ozias gets extra points for its user-friendly nicknames Oz and Ozzie. Given to around 200 boys in 2023, it has quadrupled in use since 2013.
Deriving from the Hebrew Uzziah, Ozias is the name of several minor figures in the Greek and Latin Bible, most notably the king of the ancient Kingdom of Judah. It also has a literary connection in the form of the wonderfully named Ozias Midwinter from Wilkie Collins' 19th century sensationalist novel Armadale. Several characters in the novel describe the name as 'horrible', claiming that 'no sane human being would assume such a name as Ozias', but we - and a growing number of parents - would disagree.
- Florian
Origin:
LatinMeaning:
"flowering"Description:
If Flora and Florence have returned full force, Florian, with its trendy Latinate ending, could also have a chance. Popular in Germany, Austria, Switzerland, Poland, and France, St Florian was the venerated patron saint of those in danger from water and the patron saint of firefighters.
- Cosmo
Origin:
Greek, Italian, EnglishMeaning:
"order, beauty, universe"Description:
We all heard it on Seinfeld as the long-concealed first name of Kramer, then considered a punchline. Now some pioneering parents are embracing this expansive Greek name, which makes a creative and cool choice for a baby. Influential celebrity couple Scarlett Johansson and Colin Jost chose it for their son, born in 2021, which will likely drive Cosmo up in popularity. In the UK, it currently ranks within the Top 1000 boy names and is trending upwards.
- Casimir
Origin:
Polish, SlavicMeaning:
"destroyer of peace"Description:
Casimir, a traditional name of Polish kings, could do quite well these days as we see the rise of Caspian, Cassius, Castiel, et. al. Like Leopold and Laszlo, Casimir is strong and worth considering if you've got an adventurous streak — and bet your son will too.
- Casper
Origin:
Dutch form of Jasper, PersianMeaning:
"bringer of treasure"Description:
This ancient name, also spelled Caspar, is finally shedding its ghostly image and moving into the 21st century. Popular in the Netherlands and Scandinavia, where it's sometimes shortened to Cas, Casper could ride the style coattails of cousin Jasper. Casper was one of the Three Magi who brought gifts to the infant Jesus along with Melchior and Balthasar.
- Caius
Origin:
Variation of Gaius, LatinMeaning:
"rejoice"Description:
Caius is classical and serious but also has a simple, joyful quality. There was a third century pope named Caius, as well as an early Christian writer, several Shakespearean characters, and a Twilight vampire. We would pronounce the name to rhyme with eye-us though at Cambridge University in England, where it's the name of a college, it's pronounced keys.
- Keir
Origin:
IrishMeaning:
"dark, black"Description:
Keir is a single-syllable name that packs a lot of punch, might suggest -- thanks to its similarity to the word care -- a caring person. Sir Keir Rodney Starmer is a British politician and head of the Labour Party since 2020. Keir Dullea is an American actor who starred in 2001: A Space Odyssey.
- Torin
Origin:
IrishMeaning:
"chief"Description:
Though it has a Scandinavian ring, this is an out-of-the-ordinary Irish family name. The hard 'T' at the beginning prevents it from sounding as feminine as, say, Loren. Torin's Passage was an early video game.
- Rhodes
Origin:
GreekMeaning:
"where roses grow"Description:
This is a name we've seen the potential of for some time now — A Greek island and a prestigious scholarship make for a preppy first name with the uber-stylish S ending. Needless to say we were not surprised that Rhodes cracked the Top 1000 in 2022, and we expect it to keep rising. Rhodes was recently chosen by actress Emma Roberts for her son, born in 2020.
- Luan
Origin:
Portuguese, Albanian, Vietnamese, or IrishMeaning:
"moon; lion; ethics; warrior"Description:
Luan is a handsome, unusual boy's name with surprisingly diverse origins. It's a rare Portuguese name meaning "moon", an Albanian name meaning "lion", a Vietnamese name meaning "justice; ethics", and a Gaelic name meaning "hound; warrior".
- Olin
Origin:
Swedish, Norwegian, EnglishMeaning:
"ancestor, to inherit, legacy; from the low-lying land"Description:
Distinctive yet familiar, Olin is both a Scandinavian name and an English surname. Currently a rare choice, yet reminiscent of popular options, like Oliver, Orion, and Colin.
- Orson
Origin:
Latin and EnglishMeaning:
"bear cub"Description:
In the past, Orson has felt like a one-person moniker, tied to film director Orson Welles, who dropped his given name of George in favor of his more distinctive middle. While the Citizen Kane creator seemed to own the name during his lifetime, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set too -- both Paz Vega and Lauren Ambrose have little Orsons.
- Stellan
Origin:
Swedish, meaning unknown, possibly "calm"Meaning:
"calm"Description:
Stellan is a strong, attractive, Scandinavian possible up-and-comer, known through actor Stellan Skarsgard, and his namesake, the son of Jennifer Connelly and Paul Bettany. Its trendy 'an' ending and the similarity in sound to the popular Kellen/Kellan make it all the more accessible.
- Roscoe
Origin:
NorseMeaning:
"deer forest"Description:
Fairly popular a hundred years ago but out of sight now, the quirky Roscoe deserves a place on every adventurous baby-namer's long list. It joins Rufus, Roman, Remy, Romulus, and Ray as one of the R names that sound fresh again after too many years of Robert, Richard, and Ronald.
