Alferius was a 10th and 11th-century Italian Benedictine abbot and bishop born into the noble Pappacarbone family of Salerno. After serving the Prince of Salerno, he traveled to France, where an illness led him to vow monastic life upon his recovery. Following a period at Cluny, he eventually settled near Monte Finestra to pursue a life of prayer. He became the founder of the monastery of La Trinità della Cava, which was established under the Benedictine rule.
