The Archdiocese of Munich and Freising (German: Erzbistum München und Freising, Latin: Archidioecesis Monacensis et Frisingensis) 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.
The see was canonically erected in about 739 by Saint Boniface as the Diocese of Freising, and later became a prince-bishopric. The diocese was dissolved in 1803 following the collapse of the Holy Roman Empire, although a titular bishop ruled until April 1, 1818, when Pope Pius VII elevated the diocese to an archdiocese with its new seat in Munich, rather than Freising.
