O Girls

Oceane (oh-see-EN) has been one of the chicest names in France for several years, ranking in the French Top 50. This is a sophisticated name that could easily cross the ocean, and is much more stylish than the English Ocean or Oceana.

Pretty Hebrew name that would create a strong but feminine impression, as well as a variant of the Germanic name Odilia or Ottilie.

Odessa, a Ukrainian port city, was given its name by Catherine the Great, who was inspired by Homer's Odyssey. It would make an original and intriguing choice.

Odette is the good swan in Tchaikovsky's ballet Swan Lake, a role for which Natalie Portman won an Oscar ---and it would make a particularly soigne, sophisticated yet upbeat choice, unlike some of the more dated other 'ette'-ending names.

Ukrainian figure-skating champion Oksana Baiul made it known here.

This Slavic form of the Norse name Helga is a classic in many Slavic countries, including Russia and Poland, where it currently ranks within the Top 100 girl names. It has historically ranked among the most popular names in countries including Ukraine, Latvia, Spain, France, Serbia, Greece, the US, and many more. Olga is a common name even in Scandinavian countries, such as Sweden and Norway, despite Helga being a more traditional choice. Olha is the uniquely Ukrainian variation.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four girl names starting with O on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen.

Olwen is a Welsh favorite, the name of a legendary princess in what is believed to have been the earliest Arthurian romance, and in fact one of the first recorded examples of Welsh prose.

Olwyn is a popular Welsh name that might be an alternative to the more familiar Bronwen or Rhonwen -- though in Wales the female form is usually spelled -wen and the male one -wyn.

With its relation to Mount Olympus, home of the Greek gods, and to the Olympic games, this name has an athletic, goddess-like aura, making it the perfect Olivia substitute.

Onyx is a fresh and trending gemstone name for boys, currently in the US Top 500, having climbed the charts rapidly since 2018. Now, an increasing number of girls are receiving the name, with a recent count revealing nearly 200 baby girls were called Onyx in 2023.

Floral, elegant, and bold, Ophelia re-entered the US Top 1000 in 2015 after more than 50 years off the charts. It has risen more than 700 spots since then and shows no signs of slowing down. Now in the US Top 300, could Ophelia one day become the next Olivia or Amelia?

Like many a popular name, Ornella is a theatrical creation. Italian playwright Gabriele d'Annunzio created this name for his dramatic heroine in the 1904 play La Figlia di Iorio. Ornella is a feminization of the orno or ornello, which is the Italian word for the Fraxinus Ornus, a type of tree which produces such sweet sap that it was compared to biblical manna.

Softer and more romantic than Octavia, this is a name once used when it wasn't uncommon for families to have eight children. A possible substitute for the epidemically popular Olivia.

Ottilie is trending in the UK, where the pronounced T helps the name sound pretty and delicate, rather like Amelie and Elodie. Ottilie is less popular in the US, where many Americans pronounce it as a near-homonym for "oddly".
