The Múscraighe were an important Érainn people of Munster, descending from Cairpre Músc, son of Conaire Cóem, a High King of Ireland. Closely related were the Corcu Duibne, Corcu Baiscind, both of Munster, and also the Dál Riata of Ulster and Scotland, all being referred to as the Síl Conairi in Irish and Scottish legends. A more distant ancestor was the legendary monarch Conaire Mór, son of Eterscél, son of Íar, son of Dedu mac Sin.
