1000+ Unique, Rare, and Uncommon Boy Names (with Meanings and Origins)

1000+ 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 current favorite rare and unique names for boys, with origins and meanings, ordered by their current popularity on Nameberry.

      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.

      Italian, Spanish

  3. AureliusHeart
    • Origin:

      Latin
    • Meaning:

      "the golden one"
    • Description:

      Since Aurelius was given the supermodel seal of approval by Elle Macpherson, this is one of the Roman emperor names, like Augustus, now in the realm of possibility. Like the female Aurelia and Aurora, Aurelius has a particularly warm golden aura.
  4. CaiusHeart
    • Origin:

      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.
  5. CasimirHeart
    • Origin:

      Polish, Slavic
    • Meaning:

      "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. An alternative commonly cited meaning that modern parents might prefer is "proclaimer of peace". The traditional Polish spelling of the name is Kazimir.
  6. LysanderHeart
    • Origin:

      Greek
    • Meaning:

      "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.

      Greek, Italian, English
    • Meaning:

      "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.

It was the name of three popes, appears in several Shakespeare plays, and, like all the names beginning with 'luc' relates to the Latin word for light.It was one of a limited number of forenames used in ancient Rome, and because of its meaning was often given to boys born at dawn.

      Latin and English
    • Meaning:

      "bear cub"
    • Description:

      Orson has had in the past a rotund teddy-bear image, a la Orson Welles, who early on dropped his common given name of George in favor of his more distinctive middle one, and who seemed to own it during his lifetime. No longer a single-person signature, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set--both Paz Vega and Lauren Ambrose have little Orsons.
