The Bishopric of Dorpat was a medieval prince-bishopric, i.e. both a diocese of the Roman Catholic Church and a temporal principality ruled by the bishop of the diocese.

It included areas on both sides of the Oder River around the town of Lebus. The cathedral was built on the castle hill in Lubusz and was dedicated to St Adalbert of Prague. Later, the seat moved to Górzyca, back to Lebus and finally to Fürstenwalde on the River Spree.

The terms prince-bishopric and ecclesiastical principality are synonymous with Hochstift. Erzstift and Kurerzstift referred respectively to the territory (prince-archbishopric) ruled by a prince-archbishop and an elector-archbishop while Stift referred to the territory ruled by an imperial abbot or abbess, or a princely abbot or abbess. Stift was also often used to refer to any type of ecclesiastical principality.
