Babolein was a seventh-century monk and the inaugural abbot of the monastery at Saint-Maur-des-Fossés, located near Paris. Originally a disciple of Saint Columban at the abbey of Luxeuil, he later oversaw the establishment of a new monastic community following a royal donation. He implemented a unique religious rule that combined elements of both the Columbanian and Benedictine traditions. He served as the leader of this community until his death in the late seventh century.
