The Diocese of Alife-Caiazzo () 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.

History
The old diocese of Alife was made up of twelve communes in the civil province of Caserta, subject to the  Archbishopric of Benevento. 

The name of a Bishop of Alife appears for the first time among the signatories of the Roman Synod of 499 of Pope Symmachus. Alife became a suffragan of the metropolitan archbishop of Benevento in 969, when Pope John XIII created the ecclesiastical province of Benevento.

In 1676, the city of Alife had a population of c. 1200 persons, and the diocese in addition had 18 loca (villages). The city had one monastery for men. The bishop resided, however, in a village called "Pedemonte". In 1752, the city of Alife had only 500 inhabitants. The residence of the bishop at Piedimonte had three schools, seven houses of male religious, and two convents of nuns. There were only 13 loca.

After the French
Following the extinction of the Napoleonic Kingdom of Italy, the Congress of Vienna authorized the restoration of the Papal States and the Kingdom of Naples. Since the French occupation had seen the abolition of many Church institutions in the Kingdom, as well as the confiscation of much Church property and resources, it was imperative that Pope Pius VII and King Ferdinand IV reach agreement on restoration and restitution. Ferdinand demanded the suppression of fifty dioceses. 

A concordat was finally signed on 16 February 1818, and ratified by Pius VII on 25 February 1818. Ferdinand issued the concordat as a law on 21 March 1818. On 27 June 1818, Pius VII issued the bull De Ulteriore, in which, the decision was made to suppress permanently the diocese of Alife, and to incorporate its territory into the united dioceses of Cerreta e Telese.

Protests and complaints were quickly submitted to the pope. The bishop of Alife, Emilio Gentile, the Chapter of the cathedral, the rectors of the parishes of the diocese of Alife, and the magistrates of the city all made their supplications, pointing out the antiquity of the episcopal seat, the well regarded diocesan seminary, the inconvenience and danger of regular travel over the mountains to Telese, and other considerations. Pope Pius submitted these to the Commission for the Execution of the Concordat, and to the Sacred Congregation Consistorial for examination and recommendations. Finally, on 15 January 1820, he issued the bull "Adorandi Servatoris", by which he revoked and annulled the provisions of the bull "De Ulteriore" so far as they commanded the suppression of the diocese of Alife. There was, however, an additional provision: that one and the same bishop would be the bishop of Alife and the bishop of Telese at the same time. aeque personaliter. He was to be called the bishop of "Alife e Telese".

On 6 July 1852, in the bull "Compertum Nobis", Pope Pius IX made the decision to reverse the judgment of Pope Pius VII and restore the diocese of Alife, thereby completely separating the two dioceses, and removing its territory again from the power of the bishop of Cerreto e Telese.

Consolidation of dioceses
On 18 February 1984, the Vatican and the Italian State signed a new and revised concordat, which was accompanied in the next year by enabling legislation. According to the agreement, the practice of having one bishop govern two separate dioceses at the same time, aeque personaliter, was abolished. Otherwise Caiazzo and Alise, who shared a bishop, might have become the diocese of Alife e Caiazzo. Instead, the Vatican continued consultations which had begun under Pope John XXIII for the merging of small dioceses, especially those with personnel and financial problems, into one combined diocese. 

On 30 September 1986, Pope John Paul II ordered that the dioceses of Caiazzo and Alife be merged into one diocese with one bishop, with the Latin title Dioecesis Aliphana - Caiacensis. The seat of the diocese was to be in Alife, and the cathedral of Alise was to serve as the cathedral of the merged diocese. The cathedral in Caiazzo was to become a co-cathedral, and the cathedral Chapter was to be a Capitulum Concathedralis. There was to be only one diocesan Tribunal, in Alife, and likewise one seminary, one College of Consultors, and one Priests' Council. The territory of the new diocese was to include the territory of the former separate dioceses of Caiazzo and Alife.
