Meaning & Origin

A figure in Welsh mythology.

Rhiannon is a girl's and boy's baby name of Welsh origin, from the Celtic goddess Rigantona, meaning 'divine queen' or 'great queen,' from the Celtic rīgan- (queen) — later evolved into Rhiannon of the Mabinogion, the Welsh mythological horse goddess.

Fleetwood Mac's 1975 song "Rhiannon" — one of rock's most ethereal ballads — gave this ancient Welsh name a mystical, musical identity that has never faded. Stevie Nicks described it as "a Welsh witch," and the name's combination of Celtic mythology, divine queenship, and rock legend makes it one of the most hauntingly beautiful names in the Western tradition.
