The Archbishop of Cashel was an archiepiscopal title which took its name after the town of Cashel, County Tipperary in Ireland. Following the Reformation, there had been parallel apostolic successions to the title: one in the Catholic Church and the other in the Church of Ireland. The archbishop of each denomination also held the title of Bishop of Emly. In the Catholic Church, it was superseded by the role of Archbishop of Cashel and Emly when the two dioceses were united in 2015 and in the Church of Ireland the title was downgraded to a bishopric in 1838.
