Giovanni de Surdis Cacciafronte was a 12th-century Italian Benedictine priest and bishop. Born in Cremona in 1125, he rose through the monastic ranks to become the abbot of San Lorenzo. His ecclesiastical career included serving as the Bishop of Mantua from 1174 to 1177 and subsequently as the Bishop of Vicenza until his death in 1184. Known for his loyalty to Pope Alexander III during a period of schism, he was eventually murdered in Vicenza following a confrontation with an individual he had reprimanded for embezzlement.
