Dôn is a Welsh mother goddess. She does not play a direct part in the action of the Mabinogi, though many characters in that cycle are related to her. She is the mother of Arianrhod, Gwydion, Gilfaethwy, Gofannon, Eufydd, Elestron and Amaethon. Patrick K. Ford asserts that she is the equivalent of the IrishDanu and of the Gaulish goddess "whose name is preserved in the river name Danube (Donau)".
