Riannon

Riannon is a feminine name with Celtic origins, likely derived from Rhiannon, a figure in Welsh mythology associated with horses and birds. In the Mabinogion, Rhiannon was a beautiful, magical woman who rode a swift white horse. The spelling variant Riannon maintains the melodic flow and mythological connections while offering a slightly different visual presentation. This name carries connotations of strength, independence and mystical qualities from its legendary namesake. While relatively uncommon in mainstream usage, Riannon appeals to those drawn to Celtic heritage and mythology. The name gained some recognition after Fleetwood Mac's 1975 hit song 'Rhiannon,' which helped introduce this name family to wider audiences. Riannon combines ancient roots with a contemporary sound.

Pronounced ree-AN-un.
