Unique, Rare, and Uncommon Boy Names (with Meanings and Origins)

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.

  1. Roscoe

    • Origin:

      English, Norse

    • Meaning:

      "deer forest"

    • Description:

      Fairly popular a hundred years ago but out of the US charts since 1978, the quirky yet edgy Roscoe feels very much in step with the trending o-ending boy names popular now, such as Milo, Hugo, and Otto. A Top 1000 choice in the UK (albeit near the latter end), it could make a cool alternative to Ross, Russell, Robert, and Ronan.
  2. Leopold

    • Origin:

      German

    • Meaning:

      "brave people"

    • Description:

      An aristocratic and stately Germanic route to the popular Leo, Leopold is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold I of Belgium. These days, this royal tie may be seen as a drawback to the name, owing to the cruelty of King Leopold II's rule over the Congo, though it remains popular in Austria, Poland, and France (as Léopold).
  3. Royal

    • Origin:

      English word name

    • Meaning:

      "royal"

    • Description:

      Even less subtle than Duke or Earl, this name shot up the popularity charts in 2013, the same year young Prince George was born and the craze for all things royal (and Royal) began. Today, it's a leading boys' name on Nameberry's own popularity charts.
  4. Wilbur

    • Origin:

      English, German

    • Meaning:

      "wild boar"

    • Description:

      Clunky yet cuddly, Wilbur is a stylish name in the UK where it currently sits in the Top 600, as cool as Rupert or Wilfred. Its merits are starting to be rediscovered in the US, where it was last truly popular more than a century ago. A recent year saw it given to 42 boys.
  5. Kit

    • Origin:

      English, diminutive of Christopher

    • Meaning:

      "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 back in the 2000s, while actor Kit Connor of Heartstopper fame may have introduced it to a wider audience.
  6. Elio

    • Origin:

      Italian, Spanish

    • Meaning:

      "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.
  7. Loyal

    • Origin:

      English

    • Meaning:

      "faithful, loyal"

    • Description:

      Loyal is one of the few virtue names suitable for boys, an honorable and principled Boy Scout-esque appellation with a surprisingly long and distinguished history.
  8. Ziggy

    • Origin:

      German, diminutive of Siegfried and Sigmund

    • Meaning:

      "victorious peace; victorious protection; victory"

    • Description:

      Perhaps the ultimate nicknamey name, Ziggy manages to sound cool, cutesy, spiky, and energetic all at once. It brings to mind the glam-rock of Bowie's Ziggy Stardust and the cool vibes of reggae musician Ziggy Marley, along with the contemporary-but-vintage appeal of Teddy, Mack, and Albie.
  9. Zephyr

    • Origin:

      Greek

    • Meaning:

      "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, and with its similarity in sound to the likes of Stefan or Seth, its zippy Z initial and cool Y, it is primed to rise up the US charts.
  10. Cosmo

    • Origin:

      Italian, English, Greek

    • Meaning:

      "order, beauty, universe"

    • Description:

      With a touch of celestial power, a hint of clunky charm, and the totally cool -o ending, Cosmo may well be finally shaking itself free of both the Seinfeld association (which made it a punchline of a joke) and the cartoon fairy association from The Fairly OddParents. In fact, it is in the Top 1000 in the UK and a favorite on Nameberry.
  11. Wren

    • Origin:

      English

    • Meaning:

      "small bird"

    • Description:

      Wren may not be as time-honored a bird name choice as Robin or even Lark, but it's more fashionable and fresh, with a gentle and earthy vibe.
  12. Percy

    • Origin:

      French surname from place name Perci-en-Auge

    • Description:

      Percy is an adorable old name that is finally shedding its pampered Little Lord Fauntleroy image in this new era of boys with soft yet traditionally male names like Jasper and Elijah. Originating as an aristocratic Norman name, Percy became fairly widespread in England--and to some extent in the US--as an offshoot of the fame of the poet Percy Bysshe Shelley.
  13. Casper

    • Origin:

      Dutch form of Jasper, Persian

    • Meaning:

      "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.
  14. Emrys

    • Origin:

      Welsh, variation of Ambrose

    • Meaning:

      "immortal"

    • Description:

      Magical and powerful, but gentle and approachable too, Emrys is a Welsh name which may be worth considering if you're looking for something less common that Dylan, Evan, or Morgan. An offbeat epithet of the wise wizard Merlin, it's currently in the Welsh top 100 and in the England and Wales Top 500 over all.
  15. Rhodes

    • Origin:

      Greek

    • Meaning:

      "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.
  16. Gus

    • Origin:

      Diminutive of Augustus, Angus, Gustave, Augustin, Augusten, Augustine, August

    • Description:

      Gus is a homey grandpa nickname name that can work as a short form for any of the above or stand on its own as a cutting-edge replacement for Max and Jake--though it was off the Top 1000 from 1978 until 2016, when it squeaked in at Number 999.
  17. Ivo

    • Origin:

      Germanic, Slavic

    • Meaning:

      "yew wood, archer; God is gracious"

    • Description:

      Succinct, stylish, and catchy, Ivo has the energetic impact of other names ending in -o. It is a multicultural choice with two distinct origins, and, as such, is familiar across a variety of countries, ranging from the Netherlands to Brazil, from Portugal to Czechia.
  18. Caius

    • Origin:

      Variation of Gaius, Latin

    • Meaning:

      "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.
  19. 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.
  20. Jules

    • Origin:

      French form of Latin Julius

    • Meaning:

      "youthful; soft, downy"

    • Description:

      Though Jules hasn't been on the US popularity list in fifty years, it is a current hit in its native France—where it's currently in the Top 10—and we can definitely see it making a comeback here, being far more romantic than, say, Jim.
