The Archbishop of Armagh is an archiepiscopal title which takes its name from the city of Armagh in Northern Ireland. Since the Reformation, there have been parallel apostolic successions to the title: one in the Roman Catholic Church and the other in the Church of Ireland. The archbishop of each denomination also holds the title of Primate of All Ireland.

Malachy is an Irish saint who was Archbishop of Armagh, to whom were attributed several miracles and an alleged vision of 112 popes later attributed to the apocryphal Prophecy of the Popes.
