Peter of Pappacarbone was an 11th-century Italian Benedictine abbot and bishop. Born in Salerno, he initially joined the monastery at Cava under the leadership of Leo I. After spending several years at Cluny between 1062 and 1068, he was appointed as the bishop of Policastro in 1079. He eventually resigned his episcopal position to return to the abbey at Cava de' Tirreni, where he served as abbot for many decades until his death in 1123.
