The Diocese of Sora-Cassino-Aquino-Pontecorvo (Latin: Dioecesis Sorana-Cassiensis-Aquinatensis-Pontiscurvi) is a Latin Church ecclesiastical jurisdiction or diocese of the Catholic Church in Lazio, Italy. It is exempt to the Holy See and not part of any ecclesiastical province. The current bishop of Sora-Cassino-Aquino-Pontecorvo is Gerardo Antonazzo, who was ordained a bishop on April 8, 2013 by Pope Francis.

The Diocese of Sora originated in the 3rd century.

On June 27, 1818, it was united with the Diocese of Aquino and Pontecorvo, as the Diocese of Aquino, Sora and Pontecorvo, from September 30, 1986 known as the Diocese of Sora-Aquino-Pontecorvo.

On October 23, 2014, the lands of the Benedictine territorial Abbey of Montecassino which were not part of the abbey proper were transferred by Pope Francis to this diocese. It was then renamed to its current title. The various religious institutions involved in this transfer included 53 parishes. In 2020 there was one priest for every 2,122 Catholics in the diocese.

The seat of the bishop is the Cathedral of St. Mary of the Assumption (Italian: Santa Maria Assunta) in Sora.

Both former cathedrals, St. Bartholomew the Apostle (Italian: S. Bartolomeo Apostolo) in Pontecorvo and Aquino’s Sts. Constantius and Thomas Aquinas (Italian: Santi Costanzo e Tommaso d’Aquino) Cathedral, are now ranked as co-cathedrals and were granted the status of minor basilica.
