The Tuatha Dé Danann, also known by the earlier name Tuath Dé, are a supernatural race in Irish mythology. Many of them are thought to represent deities of pre-Christian Gaelic Ireland.

Irish mythology is the body of myths indigenous to the island of Ireland. It was originally passed down orally in the prehistoric era. In the early medieval era, some myths were transcribed by Christian monks, who heavily altered and Christianised the myths. Irish mythology is the best-preserved branch of Celtic mythology.
