Origin: Irish

Meaning: One, universal; Lamb

Oona is a feminine name of Irish and Latin origin. Derived from the Latin word unus, meaning “one” or “universal,” Oona is also an Anglicized version of the Irish name Úna, which means “lamb,” and comes from the word úan. The name can be spelled as Oonagh, too, to give it that feeling of being a little closer to home in Ireland. Aside from Gaelic regions, Oona is also used throughout Scandinavian countries, where it is pronounced slightly differently. Whether you want to follow a universal theme or call baby your little lamb, Oona is an excellent choice.
