St John's Church, today known as Shangxiang Christian Church, is a Protestant church situated on Shangxiang Street in the city of Chengdu, Sichuan Province. Founded in 1909, the church had been the seat of the Anglican Bishop of West Szechwan, practically making it the cathedral of this bishopric. It has been subjected to the control of the state-sanctioned Three-Self Patriotic Church since 1954.

The history of Anglicanism in Sichuan began in 1887 when Anglican missionaries working with the China Inland Mission began to arrive from the United Kingdom. These were later joined by missionaries from the Church Missionary Society and Bible Churchmen's Missionary Society. Or according to Annals of Religion in Mianyang, in 1885, a small mission church was already founded in Mianyang by Alfred Arthur Phillips and Gertrude Emma Wells of the Church Missionary Society. Missionaries built churches, founded schools, and distributed Chinese translations of Anglican religious texts. These efforts were relatively successful and Anglicanism grew to become one of the two largest denominations of Protestant Christianity in the province, alongside Methodism.
