The Prince-Bishopric of Speyer, formerly known as Spires in English, (German: Hochstift Speyer, Fürstbistum Speyer, Bistum Speyer) was an ecclesiastical principality in what are today the German states of Rhineland-Palatinate and Baden-Württemberg. It was secularized in 1803. The prince-bishop resided in Speyer, a Free Imperial City, until the 14th century, when he moved his residence to Uddenheim (Philippsburg), then in 1723 to Bruchsal. There was a tense relationship between successive prince-bishops, who were Roman Catholic, and the civic authorities of the Free City, officially Protestant since the Reformation. The prince-provostry of Wissemburg in Alsace was ruled by the prince-bishop of Speyer in a personal union.
