The Prince-Archbishopric of Salzburg was an ecclesiastical principality and state of the Holy Roman Empire. It comprised the secular territory ruled by the archbishops of Salzburg, as distinguished from the much larger Catholic diocese founded in 739 by Saint Boniface in the German stem duchy of Bavaria. The capital of the archbishopric was Salzburg, the former Roman city of Iuvavum.

The Archdiocese of Salzburg is a Latin Church archdiocese of the Catholic Church in Austria. The archdiocese is one of two Austrian archdioceses, serving alongside the Archdiocese of Vienna.
