The Abbey of Saint-Evroul or Saint-Evroul-sur-Ouche is a former Benedictine abbey in Normandy, located in the present commune of Saint-Evroult-Notre-Dame-du-Bois, Orne, Normandy. Its name refers to its founder, Ebrulf, who founded a hermitage in the forest of Ouche around 560. The abbey was rebuilt around 1000.
Robert de Grantmesnil served as abbot of Saint-Evroul, which he helped restore in 1050. He had become a monk at Saint-Evroul before becoming its abbot.
