The Prince-Bishopric of Basel (German: Hochstift Basel, Fürstbistum Basel, Bistum Basel) was an ecclesiastical principality within the Holy Roman Empire, ruled from 1032 by prince-bishops with their seat at Basel, and from 1528 until 1792 at Porrentruy, and thereafter at Schliengen. As an imperial estate, the prince-bishop had a seat and voting rights at the Imperial Diet. The final dissolution of the state occurred in 1803 as part of the German Mediatisation.
