List of bishops and archbishops of Mainz

The Diocese of Mainz was governed by bishops until 745 when it was elevated in rank to an archbishopric. By the 10th century, the archbishops had secular jurisdiction over a territory of the Holy Roman Empire. This was the future Electorate of Mainz. From the 13th century, the archbishops were first in precedence among the prince-electors of the empire and ex officioarchchancellor. Their secular and spiritual jurisdictions, however, did not coincide geographically.

In church hierarchy, the archbishop of Mainz was the primas Germaniae.
