Lugaid Luaigne, son of Finnat Már, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He came to power after killing his predecessor, and his father's killer, Bresal Bó-DÃÂbad, and ruled for five or fifteen years, before he was killed by Congal Cláiringnech. The Lebor Gabála ÃÂrenn synchronises his reign with that of Ptolemy X Alexander I (110âÂÂ88 BC) in Egypt. The chronology of Geoffrey Keating's Foras Feasa ar ÃÂirinn dates his reign to 140âÂÂ135 BC, that of the Annals of the Four Masters to 199âÂÂ184 BC.
Although presented as an ancestor of the Eóganachta in later medieval genealogies, Lugaid is regarded by T. F. O'Rahilly as one of several late emanations of Lugaid LoÃÂgde, ancestor of the Corcu LoÃÂgde.
