539 Boy Names That Start With O (with Meanings and Popularity)
Boy names that start with O are on the way up, with old-timer Oliver and on-trend Owen leading the charge.
In Britain, the O initial is out on top for both boys and girls at the moment, with Olivia atop the girls' list and Oliver joined near the top of the boys' chart by amiable Oscar. Along with Oliver and Owen, other O names for boys in the US Top 500 include Oscar, Omar, Orion, Odin, Oakley, and Omari.
It's true that on the whole, we prefer our o's at the end of boys' names (as in popular Berry favorites Milo, Leo, and Hugo), but who's to say that you can't have both? Otto, Orlando, and Othello all rank in the Top 1000 baby names here on Nameberry... or how about Oslo, Orsino, or Octavio?
Original O names for boys trending now include Otis, Ozias, and Oakes.
Here, our full selection of boy names that start with O, ordered by their current popularity on Nameberry.
