The Roman Catholic Archdiocese of Armagh (Latin: Archidioecesis Ardmachana; Irish: Ard-Deoise Ard Mhacha) is a Latin ecclesiastical territory of the Catholic Church in Northern Ireland. The ordinary is the Archbishop of Armagh, who is also the metropolitan of the ecclesiastical province of Armagh and the Catholic Primate of All Ireland. The mother church is St Patrick's Cathedral. The claim of the archdiocese to primacy rests upon its establishment by Saint Patrick circa 445. It was recognised as a metropolitan province in 1152 by the Synod of Kells. The incumbent archbishop is Eamon Martin since 2024. Since 2019, the auxiliary bishop has been Michael Router.
