130 boy names that start with 'O'

O, say can you see ... baby boy names that start with "O"?

Chances are, you'll be seeing a lot more of them, though "O" remains a distinctive and unusual choice for a first initial.

Oliver and Owen are ranked Nos. 3 and 19, respectively, on the Social Security Administration's official list of most popular baby names in 2023.

Oscar (finally overcoming that "Sesame Street" grouchy vibe), Omar and Otto are also on the most popular list, though all three are much more rare.

Many trendy names have an "O" as the final syllable — think Leo, Arlo, Mateo and more — but a name that begins with "O" will usually strike a more uncommon chord.

“If you choose an ‘O’ name that isn’t Owen or Oliver, it’s probably going to be unusual,” Wattenberg says. “There aren’t many traditional ‘O’ names.”

For an up-and-coming "O" name, consider a more ancient source. The name Obadiah comes from the Bible.

“Oliver and Owen have really dominated in the past generation. But we’re seeing more Obadiahs, which is a biblical name," Laura Wattenberg, creator of Namerology, tells TODAY.com.

The names Ozzy and Otto are also picking up steam, according to Wattenberg. Oslo, as in the capitol of Norway, is is another “O” name that is gaining in popularity.

“Geographic names, like Oslo or Cairo, are trendy right now,” Wattenberg explains.

Famous men with “O” names throughout history include: Owen Wilson, Odell Beckham Jr., Oscar Wilde, Orlando Bloom, Orson Welles, Otis Redding and Olivier Martinez.

Celebrities who have chosen “O” names for their sons include: Odin (Nick Carter), Oliver (Dylan Dreyer), Onyx (Iggy Azalea) Ozzie (Mandy Moore), Oscar (Gillian Anderson), Otis (Jason Sudeikis), Ozzie (Max Greenfield), Ode (Jena Malone), Odie (Ashley Williams), Orson (Lauren Ambrose) and Oskar (Nate Berkus).
