The Diocese of Latina-Terracina-Sezze-Priverno is a Latin Church ecclesiastical territory or diocese of the Catholic Church in Lazio, Italy. It was established under this name in 1986. It is the continuation of the Diocese of Terracina, Priverno e Sezze, whose existence was confirmed by Pope Honorius III in 1217, as a joining of the Diocese of Terracina with the Diocese of Priverno and the Diocese of Sezze under a single bishop. It is immediately exempt to the Holy See.

Epaphroditus is a New Testament figure appearing as an envoy of the Philippian church to assist the Apostle Paul. He is regarded as a saint of the Eastern Orthodox Church and the Catholic Church, first Bishop of Philippi, and of Andriaca, and first Bishop of Terracina, Italy. There is little evidence that these were all the same man.
