The Archdiocese of Munich and Freising is a Latin Church ecclesiastical territory or diocese of the Catholic Church in Bavaria, Germany. It is governed by the Archbishop of Munich and Freising, who administers the see from the co-cathedral in Munich, the Frauenkirche. The other, much older co-cathedral is Freising Cathedral.

A co-cathedral is a cathedral church which shares the function of being a bishop's seat, or cathedra, with another cathedral, often in another city. Instances of this occurred in England before the Protestant Reformation in the dioceses of 'Bath and Wells', and of 'Coventry and Lichfield'. These two dioceses were each named for both cities that served as bishop's seats.
