Benignus was an archbishop who led the see of Milan between 465 and 472. Likely born into a noble Milanese family, he received his education in Rome before being elected to his episcopal position. During his tenure, he participated in the Roman synod of 465 under Pope Hilarius and may have been involved in the consecration of Epiphanius, the bishop of Pavia. He also played a role in efforts to mediate conflicts between Anthemius and the leader Ricimer.
