Labraid Loingsech (English: the exile, mariner), also known as Labraid Lorc, son of Ailill Áine, son of Lóegaire Lorc, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He was an ancestor of the Laigin, who gave their name to the province of Leinster. An early dynastic poem calls him "a god among the gods", suggesting he may once have been an ancestor-deity of the Laigin.
