The Cathedral of the Immaculate Conception, commonly referred to as Ping'anqiao Catholic Church, is the Roman Catholic cathedral of the Diocese of Chengdu, situated on Xihuamen Street, Qingyang District, in Sichuan's capital city of Chengdu.

The construction of the cathedral started in 1897, under the supervision of Jacques-Victor-Marius Rouchouse, a French missionary of the Paris Foreign Missions Society and the first bishop of the Diocese of Chengdu, who was appointed to supervise the work by Bishop Marie-Julien Dunand.

[2][3] The English political economist Audrey Donnithorne was baptized at this cathedral after converting from Anglicanism to Roman Catholicism in 1943.

Built in a cruciform design with a façade of neo-Byzantine style, the cathedral and its surrounding buildings constitute the Chinese character "悚" meaning "fear", representing "The beginning of wisdom is fear of the Lord" (Proverbs 9:10).

The right part of the character means "rule", which represents the function of this building as a cathedral, as Jesus said in the Gospel: "Amen, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven" (Matthew 18:18).
