Leobinus was a 5th and 6th-century religious leader who served as a hermit, abbot, and bishop. Born into a peasant family in Poitiers, he initially lived as a hermit before joining the monks at Micy Abbey. After his ordination as a priest, he was chosen to lead Brou as its abbot. In 544, with the approval of King Childebert I, he succeeded Etherius to become the Bishop of Chartres.
