Hugh Murdac was an English clergyman and canon of York Minster in the 12th and 13th centuries. Murdac was the nephew of Henry Murdac, the Archbishop of York. Hugh was a canon of the cathedral chapter of York Minster before 1153, holding the prebend of Driffield. He last occurs as a simple canon in 1198. In 1201 he was elected Archdeacon of Cleveland by the cathedral chapter but his election was opposed by Geoffrey, the archbishop. Geoffrey excommunicated Murdac and appointed William of Ely instead. Murdac founded the priory of St Andrew at York.
