Girl Names Starting with O
An O as an initial letter creates a round, open sound. Since given names starting with O are rarer than those with A or M, they often stand out right away on name lists. Whether short and Nordic or long and Romance—here you will find an overview of common and rare girl names with this vowel.
The Names
- Oana: The Romanian form of Johanna; the Hebrew root means "God is gracious".
- Océane: A French given name that traces directly back to the Greek word for "ocean".
- Octavia: Traces back to the Roman name Octavius. The Latin root "octavus" means "the eighth".
- Oda: An old German name from Old High German. The syllable "ot" stands for "property" or "wealth".
- Odette: The French diminutive of Oda or Odilia, thus sharing the Germanic meaning "property" or "inheritance".
- Odilia: An extended form of Oda, likewise based on the Old High German word for "wealth".
- Odina: The origin of this name is not definitively clear. It is widely interpreted as a feminine form of the Norse god Odin, but it can also be a variant of Oda.
- Ofelia / Ophelia: Traces back to the Greek word "ophelos", which means "help" or "benefit".
- Oksana / Oxana: The Ukrainian and Russian form of the Greek name Xenia, documented with the meaning "the hospitable".
- Olena: The Ukrainian variant of Helena. The Greek root is usually translated as "sunbeam" or "light".
- Olesya: A Slavic given name whose exact derivation is unclear. It is often classified as a pet form of Alexandra or of names containing the syllable "Oleg"; a single blanket meaning would be too imprecise here.
- Olga: The East Slavic form of the Old Norse name Helga, which means "the holy" or "the consecrated".
- Oline: In the Scandinavian linguistic area, a documented short form of names ending in "-oline", such as Caroline or Nikoline.
- Olivia: Traces back to the Latin word "oliva" and means "the olive tree" or "the olive branch".

- Ona: A short name with different origins that must be explained separately. In Lithuanian, it is the documented form of Anna; in Catalan, the word means "wave".
- Oona: Both an Irish and a Finnish name history are documented for this name. In Irish, it traces back to "uan" (lamb); in Finland, it is considered a variant of Anna.
- Oriana: A name from the Romance language area. The frequently mentioned translation "the golden one" is an interpretation based on the Latin "aurum" (gold), but the exact historical emergence is not confirmed.
- Orla: Traces back to the Irish name Órlaith. The Gaelic word elements mean "gold" and "princess" or "ruler".
- Ornella: An Italian given name that arose in the early 20th century as a literary name creation. It is derived from the Italian "ornello" (flowering ash).

The Vowel O in Everyday Life: Pronunciation and Combinations
A given name with the initial letter O brings along a few linguistic characteristics that you should consider when making your choice. First, in German there is an audible difference between the long O (as in Oda or Oline) and the short O (as in Olga or Ottilie). It is best to speak the name out loud multiple times to test which sound matches your last name better.
In addition, very many girl names starting with O end with an A (such as Olivia, Oksana, Ofelia). This O-A frame creates a very open visual and phonetic impression. If your last name also ends with an A, this can sound harmonious, but in some cases it can also blend together slightly when spoken. In the HeyName app, you can specifically set the filter for the initial letter O and display your favorites directly alongside your last name to review the visual appearance and the full name.
The Next Step in Finding a Name
If you like the initial letter O, it is best to create a shared shortlist. Connect your devices via an invite in HeyName and rate names independently of each other. Names that you both mark as favorites will automatically appear as your shared matches. That way, you quickly see whether you are on the same page regarding Nordic, Romance, or Slavic O names, and you can then discuss this closer selection in concrete terms.
