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. Leopold

    • Origin:

      German

    • Meaning:

      "brave people"

    • Description:

      This aristocratic, somewhat formal Germanic route to the popular Leo is a royal name: Queen Victoria used it to honor a favorite uncle, King Leopold of Belgium. Though Leopold sounds as if it might be a leonine name, it's not really a relative of such choices as Leon, and Leonard.
  2. 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.
  3. Phineas

    • Origin:

      English, Egyptian

    • Meaning:

      "the Nubian"

    • Description:

      Phineas is the English variation of Phinehas, a Hebrew name likely derived from the Egyptian name Pa-nehasi. Pa-nehasi, meaning "the Nubian" can also be translated as "the bronze-colored one." The Egyptians distinguished themselves from their Nubian neighbors through differences in skin tone.
  4. Roscoe

    • Origin:

      Norse

    • Meaning:

      "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.
  5. Wilbur

    • Origin:

      German

    • Meaning:

      "resolute, brilliant"

    • Description:

      Wilbur is a stylish name in the UK whose merits are just starting to be discovered in the US. Wilbur, the loveable pig who Charlotte of the Web called Some Pig, is an inspirational hero. And Wilbur and Orville Wright were early aviationists.
  6. Rafferty

    • Origin:

      Irish

    • Meaning:

      "floodtide, abundance, prosperity"

    • Description:

      Jaunty and raffish, Rafferty is one of the most engaging of the Irish surnames, used by Jude Law and Sadie Frost for their son. Fortunately, it doesn't still go by its original form: O'Raighbheartaigh.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. 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.
  12. Ozias

    • Origin:

      Greek, Hebrew

    • Meaning:

      "my strength is God"

    • Description:

      A cool Biblical option that entered the US Top 1000 for the first time ever in 2024, Ozias gets extra points for its user-friendly nicknames Oz and Ozzie or Ozzy. Given to around 280 boys in 2024, it is five times more popular than it was in 2014.
  13. 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.
  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. Aurelius

    • Origin:

      Latin

    • Meaning:

      "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 with a golden hue, Aurelius is grounded by its similarity to rising stars Aurora, Aurelia, and Atticus.
  16. Reuben

    • Origin:

      Hebrew

    • Meaning:

      "behold, a son"

    • Description:

      Reuben is derived from the Hebrew words ra’a, meaning "to see, to understand," and ben, "son." As a phrase it translates to "behold, a son." In the Bible, Reuben is Jacob's first-born son by Leah and the founder of one of the tribes of Israel.
  17. Arden

    • Origin:

      English

    • Meaning:

      "valley of the eagle; high"

    • Description:

      Arden is a gender-neutral name that's sleek and stylish but always seems to bob just below the surface of popularity, despite ticking all the boxes with its fashionable two-syllable, N-ending shape and its awesome nature-inspired meanings. In recent US statistics, 51 percent of the babies named Arden were boys to 59 percent girls.
  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. Angus

    • Origin:

      Anglicized form of Aonghus, Aonghas, Gaelic

    • Meaning:

      "one strength"

    • Description:

      Angus is a traditional yet stylish choice in the UK, especially in Scotland. And it's a cool choice for US parents too, particularly those whose roots go back to Glasgow. The ancient Celtic form Oenghus has important historical overtones in Scotland, and the Gaelic form Aonghas is associated with two distinguished modern poets. In Irish folklore, Angus Og is a chieftain-lord who used his magical powers for the pleasure and prosperity of mankind--and in Irish myth, Aonghus was the god of love and youth.
  20. 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.
