St John's Cathedral, today known as Gospel Church, is a Protestant church situated on Yangtianjing Street in the county-level city of Langzhong, Nanchong, Sichuan Province. Founded in 1908, the church had been the Anglican cathedral, originally designated as a pro-cathedral, of the Szechwan Diocese (and later of East Szechwan) of the Church in China, and the largest Anglican church in Southwest China. It has been subjected to the control of the state-sanctioned Three-Self Patriotic Church since 1954.
