List of bishops of Hildesheim

Between 1235 and 1803 the bishops simultaneously officiating as rulers of princely rank (prince-bishop) in the Prince-Bishopric of Hildesheim (German: Hochstift Hildesheim), a state of imperial immediacy within the Holy Roman Empire.

Between 1235 and 1803 the elected and papally confirmed bishops of the Hildesheim See were additionally imperially invested princely power as prince-bishops.

In 1235 part of the Hildesheim diocesan territory, the episcopal and capitular temporalities (Stift) were disentangled from the Duchy of Brunswick and Lunenburg and became an own territory of imperial immediacy called Prince-Bishopric of Brunswick and Lunenburg (German: Hochstift Hildesheim), a vassal of the Holy Roman Empire.

Papally confirmed bishops were then invested by the emperor with the princely regalia, thus the title prince-bishop.

However, sometimes the respective incumbent of the see never gained a papal confirmation as bishop (lacking canonical qualification; e.g. Ferdinand of Bavaria and Frederick of Denmark), but was still invested the princely regalia.
