Clemente da Osimo was a 13th-century Italian priest belonging to the Order of Saint Augustine. Born in 1235, he rose through the ranks of his religious community, eventually serving two terms as the Prior General. He is primarily recognized for his efforts to reform the order's governance and for promoting education among the clergy. After his death in Orvieto in 1291, his reputation for sanctity led to his beatification by Pope Clement XIII in 1761.
