Origin: Old Norse
The name is a feminine form of the Old Norse, Arni, meaning, (eagle).
The name also appears in Russia, and is often listed as a form of Irina, but is most likely a borrowing from the Old Norse. The name was popularized in Russia by Alexander Pushkin, who had a grandmother of the same name.
As of 2010, Arina was the 4th most popular female name in both the Faroe Islands and in Estonia.
