The Diocese of Alife-Caiazzo (Latin: Dioecesis Aliphana-Caiacensis o Caiatina) is a Roman Catholic ecclesiastical territory in Campania, southern Italy, created in 1986. In that year the historic Diocese of Alife was united with the Diocese of Caiazzo. The diocese is a suffragan of the Archdiocese of Naples.
In 2014 the diocese had one priest for every 1,104 Catholics.
The old diocese of Alife was made up of twelve communes in the province of Caserta, Archbishopric of Benevento. The name of a Bishop of Alife appears for the first time among the signatories of the Roman Synod of 499, in the time of Pope Symmachus (Clarus episcopus Ecclesiœ Allifanœ subscripsi); see "Monumenta Germaniæ Historica," auct. Antiquiss., XII, 400.
