Hugh McOwen O'Conor (Irish: Aedh mac Eoghan Ó Conchobair) was king of Connacht in late medieval Ireland.
He is the person addressed in the poem Cóir Connacht ar chath Laighean and in the poem An tu aris a raith Theamhrach by Aonghus Ruadh Ó Dálaigh.
Upon the death of Magnus in 1293, Cathal briefly reclaimed the kingship, but some months later was killed.
In 1293 John FitzThomas FitzGerald, 4th Lord of Offaly built a castle at Sligo.
[1] In 1309 O' Conchobair was killed by Aedh Breifnech, of the Clan Murtagh O'Conor, who held the kingship for one year.
