Lugaid Mac Con, often known simply as Mac Con, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He belonged to the Corcu Loígde, and thus to the Dáirine. His father was Macnia mac Lugdach, and his mother was Sadb ingen Chuinn, daughter of the former High King Conn Cétchathach. Mac Con may be to some extent identical with another legendary King of Tara from the Dáirine, Lugaid Loígde.
