The Princely Abbey of Stavelot-Malmedy, also Principality of Stavelot-Malmedy, sometimes known with its German name Stablo, was an ecclesiastical principality of the Holy Roman Empire. Princely power was exercised by the Benedictine abbot of the imperial double monastery of Stavelot and Malmedy, founded in 651. Along with the Duchy of Bouillon and the Prince-Bishopric of Liège, it was one of only three principalities of the Southern Netherlands that were never part of the Spanish, later Austrian Netherlands, which after 1500 were assigned to the Burgundian Circle while the principalities were assigned to the Lower Rhenish Imperial Circle.
