The Imperial Abbey of Corvey or Princely Abbey of Corvey was a Benedictine abbey on the River Weser, 2 km northeast of Hoxter, now in North Rhine-Westphalia, Germany. It was one of the Imperial abbeys of the Holy Roman Empire from the late Middle Ages until 1792 when the abbey was dissolved and Corvey converted into a prince-bishopric. It was in turn secularized in 1803 and absorbed into the newly created Principality of Nassau-Orange-Fulda. In 2014, the former abbey was listed as a UNESCO World Heritage Site.
