The Goddess Rhiannon is an important figure from Welsh mythology

Rhiannon is a feminine Welsh given name (pronounced [r̥iˈanɔn]) possibly derived from the Old Celtic title Rigantona, meaning great queen. While the goddess Rhiannon is a major figure in Welsh mythology, and a main protagonist in the Mabinogi, Rhiannon was not a popular given name in Wales until the 20th century. It rose in use throughout the Anglosphere after 1975, following the release of the hit song "Rhiannon" by Fleetwood Mac.
