Roman Catholic Diocese of Chengdu

The Roman Catholic Diocese of Chengdu (formerly spelt Chengtu) (Latin: Dioecesis Cemtuana; simplified Chinese: 天主教成都教区; traditional Chinese: 天主教成都教區) 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, based in Chengdu, covers 4 cities, namely, Chengdu (Tchen-tou-fou), Deyang (Te-yang-hien), Guangyuan (Koang-yuen-hien) and Mianyang (Mien-tcheou-hien), and 37 districts and counties, totaling an area of 54,900 square kilometers.

One of the headquarters of the Spanish Redemptorist missions in Sichuan was based in the Apostolic Vicariate of Chengtu.
