Peter I (Latin: Petrus) was the bishop of Benevento from 887 or 894 until at least 902. His pontificate was marked by rapid political shifts, with Benevento successively under Byzantine (891–895), Spoletan (895–897) and Lombard rule. Peter was imprisoned and exiled a first time in 895. He served as the regent and de facto ruler of the Principality of Benevento between 897 and 900. In 902, he was proclaimed prince by the people but refused the office and went into exile a second time. He died in 914, possibly still in exile. He was buried in Benevento
