Great queen; a variant form of Rhiannon, from the Welsh 'Rigantona', meaning divine queen
Rianna is a girl's name of Celtic origin, closely related to the Welsh name Rhiannon, which derives from the ancient Celtic 'Rigantona' — a compound of 'rigan' (queen) and a divine suffix, effectively meaning 'great queen' or 'divine queen'. Rhiannon herself is one of the most captivating figures in Welsh mythology, a supernatural horsewoman from the Mabinogi who rides a white horse and is associated with birds, enchantment, and enduring patience. Rianna is a streamlined, contemporary form that retains all its regal, mythological heritage with a cleaner spelling.
Rianna draws on one of the most powerful female figures in the entire Celtic mythological tradition. The original Rhiannon in the Mabinogi is a complex, dignified character — wrongly accused, unjustly punished, and ultimately vindicated — whose story has resonated for nearly a thousand years. Fleetwood Mac's iconic 1975 song 'Rhiannon' cemented the name's place in modern cultural memory.
Regal, resilient, and enchanting — Rianna tends to be creative and independent, a person whose natural dignity makes others sit up and pay attention.
