Diocese of Zhangjiakou

The Diocese of Zhangjiakou is a religious jurisdiction of the Catholic Church in the province of Hebei, China. It is a diocese of the Latin Church and its episcopal see is the city of Zhangjiakou in northwestern Hebei. It was created on 10 September 2025 by Pope Leo XIV, coinciding with the disestablishment of the Diocese of Xuanhua and the Diocese of Xiwanzi, as well as the consecration of Zhangjiakou's first bishop, Joseph Wang Zhengui. It is in the ecclesiastical province of the Archdiocese of Beijing.

Following the proclamation of the People's Republic of China, the underground church – comprising Catholics opposed to the ruling Chinese Communist Party and its affiliated Chinese Catholic Patriotic Association (CCPA) – maintained the Diocese of Xuanhua and the Diocese of Xiwanzi. The CCPA also operated its own jurisdiction in the territory, the Diocese of Zhangjiakou, which was not recognized as canonical by the Vatican. In 2018, an agreement between the Chinese government and Vatican set up a system for the appointment of bishops approved by both parties. Leo XIV's announcement, which suppressed the sees at Xuanhua and Xiwanzi while also erecting a canonical Diocese of Zhangjiakou, was the first time under Leo XIV that diocesan borders were redrawn to match Chinese civil boundaries and the first time such a reorganization was mutually agreed upon between the Vatican and Chinese government. Wang was consecrated following approval under the 2018 agreement's framework.
