The Diocese of Caiazzo is a former Roman Catholic ecclesiastical territory in the province of Caserta, southern Italy, abolished in 1986, when it was united into the Diocese of Alife-Caiazzo. It was a suffragan of the archdiocese of Capua.
According to legend, Christianity was introduced by St. Priscus, first Bishop of Capua. The first known bishop of Caiazzo was Arigisus, the exact time of whose episcopate is uncertain; however, as the name indicates, it could not have been before the beginning of the seventh century, when the Lombards settled in that region.
Others were:
Stefano, who had been Abbot of S. Salvatore in Capue (died 1025), and his successor Ferdinando;
Jacopo (died 1253), exiled by Emperor Frederick II;
Giuliano Frangipane, elected in 1472;
Vincio Maffa, elected in 1507, theologian at the Fifth Lateran Council (1512);
Ascanio Parisani, elected in 1528
Fabio Mirto, elected in 1537, who took part in the Council of Trent, and was Apostolic nuncio to Paris at the time of his death (1587);
Ottavio Mirto Frangipani, elected in 1572;
Orazio Acquaviva, who was captured by the Turks at the battle of Lepanto;
Taddeo, elected in 1641.
