Rhiannon is associated with the meaning “Divine queen, great queen” — a beautiful sentiment to see brought to life in your child’s room.
Rhiannon comes from the ancient Celtic language of Wales. Linguists believe it derives from the old Brittonic word "Rigantona," which roughly translates to "Great Queen" or "Divine Queen." The root "riga" means queen or ruler, connecting it to a class of names tied to sovereignty and power in early Celtic culture.
