Áed Ua Conchobair or Áed in Gai Bernaig was the King of Connacht, and reigned from 1046 to 1067. He was the son of Tadg in Eich Gil. A member of the Ó Conchobhair family, Áed ascended to the throne after King Art of Connacht was killed by the Cinel Conaill in 1046. This was "the second year after his (King Art) having plundered Cluain-mic-Nois." In December 1061, Áed survived an invasion from a branch of the Uí Briúin dynasty, which led to the expulsion of the branch to Iar Connacht. The same branch, the Muintir Murchada, would later take the life of Áed's son, in May 1062.
