Oh my, oh my, there’s nothing like girl names that start with O. A dramatic letter fit for the stage, the letter O is in a league of its own. Unlike most other vowel monikers that are seen as soft and serene, O names for girls are mostly bold and assertive. There are names like the great Oceana and Orianna as well as the Greek goddess of Olympia all waiting for their time on center stage.

Of course there are plenty of softer baby girl names that start with O like everyone’s favorite darling Olivia. There are also her sisters Olive and Oliva that are just as beautiful as their more well-known relative.

If you look a little deeper into unique girl names that start with O, you’ll find such stunners as Oona and Ora. Baby girl names starting with O are fairly uncommon and bursting with opportunities to spin off of popular naming trends. Rather than Raven, why not try out October for a similar vibe? For a rarer twist on the unisex name trend, give Ollie a chance.

Girl names that start with O are versatile, coming from many backgrounds and styles. Whether you’re a vintage namer or more of a modern maven, you’ll find great girl names that start with O.
