Roman Catholic Diocese of Chengdu

The Roman Catholic Diocese of Chengdu (formerly spelt Chengtu) (Dioecesis Cemtuana; ) is a suffragan Latin Catholic diocese in the ecclesiastical province of Chongqing covering southwestern China's Sichuan area, yet depends on the missionary Roman Congregation for the Evangelization of Peoples.

Established on 15 October 1696 as the Apostolic Vicariate of Szechwan, its episcopal see is the Cathedral of the Immaculate Conception (colloquially known as Ping'anqiao Church) located in the city of Chengdu. The Diocese of Chengdu is the first bishopric of the Catholic Church in Sichuan (Szechwan), since the separation of the mission's eastern territory in 1856, it was designated Western Szechwan Mission.
