Old-School O-Names for Baby Girls

Old girl names starting with o

Picking a name is one of the most thrilling parts of welcoming a baby, but with endless options to choose from and the never-ending stream of opinions that everyone feels they need to share, it can also prove a daunting endeavor.

If you're looking for old-fashioned girl names starting with the letter O, here's a handy list of names to help you get started on your quest for the perfect moniker for your baby girl. Whether your dream O-name is a vintage charmer with a nature twist (Olive) or a gemstone-inspired appellation dripping with retro charm (Opal), this list is for you. Happy naming!

Olive

Why not draw inspiration from nature and name your baby girl after a tree that doubles as a symbol of peace?

Ophelia

The epitome of "what's old is new again".

Opal

If you you're into jewel and gemstone names, this one has vintage charm to spare.

Odessa

This O name is all about vintage femininity and elegance.

Ollie

A sweet and sassy blast-from-the-past with a gender-bending vibe.

Olga

A straightforward Slavic classic at the height of its popularity in 1920s' America. Eastern Orthodox and Roman Catholic parents may prize the link to Saint Olga of Kiev.

Ora

Yet another short, old-fashioned O name that has been largely ignored by today's parents.

Ona

An all-but-lost O-name with a vintage feel.

Ottilie

A beautiful vintage name that disappeared from the baby naming lexicon in the second half of the twentieth century but that is now being revived by some forward-thinking parents.

Ola

Has Ola been out of vogue long enough to sound young and interesting again? You decide.

Oma

Not only does this name sound like it belongs to a grandmother or a great-grandmother, it also means "grandmother" in German.

Ouida

If you're a daring baby namer looking for an off-the-grid vintage name with a literary twist, this could be it—Ouida was the pseudonym of the late Victorian novelist Maria Louise Ramé, and was occasionally heard on American baby girls in the 1920s.
