Rhiannon is a feminine Welsh given name (pronounced [r̥iˈanɔn]) possibly derived from the Old Celtic title Rigantona, meaning great queen. It is borne by Rhiannon, a major figure in Welsh mythology, but was not in common use as a given name until the 20th century.[1] It rose in use in the Anglosphere after the release of the 1975 song "Rhiannon" by Fleetwood Mac.[2]
