The Archdiocese of Cashel and Emly (Irish: Ard-Deoise Chaisil agus Imligh) is a Latin diocese of the Catholic Church located in mid-western Ireland, and the metropolis of the eponymous ecclesiastical province.

Since the Papal Legate, Giovanni Paparoni, awarded the pallium to Donat O'Lonergan in 1158, his successors ruled the ecclesiastical province of Cashel – also sometimes known as Munster – until 26 January 2015.
