Fiona
Fiona is a feminine given name. The name arose in Scotland and Ireland but has also become popular in England. It can be considered either a Latinised form of the Gaelic word fionn, meaning "white", "fair". or an Anglicisation of the Irish name Fíona (derived from an element meaning "vine"). The Scottish Gaelic feminine name Fionnghal (and variants) is sometimes equated with Fiona.

Fiona was the 49th most popular name for baby girls born in 2008 in Germany. Fiona was tied for third place in the ranking of most popular names for baby girls born in Liechtenstein in 2008. The name was the 347th most popular name for girls born in the United States in 2008, where it has ranked among the top 1,000 most popular names for girls since 1990 and among the top 500 since 1999. The name Fiona has been particularly popular for girls of Asian or Pacific Islander descent in New York City, where Fiona ranked as the ninth most popular name for girls from those groups in 2007.
