Flidais is a Goddess described in early Irish literature. She is a shape-shifter and member of the Tuatha Dé Danann, known by the epithet Foltchaín ("beautiful hair"). In the Middle Irish glossary, Cóir Anmann ("Fitness of Names"), she is said to be the wife of the legendary High King Adamair and the mother of Nia Segamain, who by his mother's power was able to milk deer as if they were cows. She is considered a Hunting Goddess.
