The Bishops of Regensburg (German: Bischöfe von Regensburg; Latin: Episcopi Ratisbonensis or Episcopi Ratisponensis) are bishops of the Roman Catholic Diocese of Regensburg in Bavaria, Germany.^[1][2] The seat of the bishops is Regensburg Cathedral.

The diocese was founded in 739. The bishops were Princes of the Holy Roman Empire, ruling a territory known as the Prince-Bishopric of Regensburg. They were not among the most powerful Prince-Bishops, due to the existence of other reichsfrei authorities in Regensburg^[3] that prevented them from consolidating a major territorial base.

With the dissolution of the Archbishopric of Mainz on that territory's annexation by France in 1802, the Bishopric of Regensburg was elevated to the Archbishopric of Regensburg. It was part of the Principality of Regensburg, ruled by the Prince-Archbishop Karl Theodor Anton Maria von Dalberg. The end of the Holy Roman Empire in 1806 and its aftermath saw the end of the territorial claim of the bishops. With the death of Dalberg in 1817, the archdiocese was downgraded to being a suffragan of the Archbishops of Munich and Freising.

Itinerant bishops before the foundation of the diocese:

• Saint Emmeram (to 652)
• Saint Rupert (about 697) (uncertain)
• Saint Erhard (about 700)
