50 Boy Names Starting With “O” (2024)

Omar, Odin and Oakley, oh my!

There’s a whole lot of O-riginal goodness in these names, and they’re pretty fun to say, too. While names that start with O are more popular with our British pals across the pond, they’re starting to increasingly enter the baby name lexicon here in the States as well.

Let’s start with Omar–this popular player in the Arab world means “speaker” in Hebrew and “flourishing” or “long-lived” in Arabic. A favorite among African-Americans in the U.S., its popularity peaked here around 2007 at 131 on the list of top baby names.

For Norse mythology lovers, you can’t go wrong with Odin. This Scandinavian name pays homage to Odin, the king of the Norse gods himself, and also conjures images of frenzy, rage, and inspiration. It’s a powerful and unique name that’s perfect for energetic little boys.

If you want to go a hipper route, try Oakley or Orion. The former is of Old English origin and means “meadow of oak trees,” while the latter is an obvious nod to the constellation Orion.

If you just want a classic moniker, though, go with Oliver. Like Oakley, this Latin name simply means “olive tree,” and has a few popular variants including Olivia and the Spanish Oliviero.

Check out our long list below of boy names starting with O that will definitely have you saying, “Oh, baby!”
