In Gaelic myth, the Cailleach is a divine hag and ancestor, associated with the creation of the landscape and with the weather, especially storms and winter. The word literally means 'old woman, hag', and is found with this meaning in modern Irish and Scottish Gaelic, and has been applied to numerous mythological and folkloric figures in Ireland, Scotland, and the Isle of Man. In modern Irish folklore studies, she is sometimes known as The Hag of Beara, while in Scotland she is known as Beira, Queen of Winter.

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.
