The Roman Catholic Diocese of Jehol[1] (Latin: dioecesis Geholensis), also known in Chinese as Rehe or Jinzhou, is a diocese in the ecclesiastical province of Shenyang in China, covering part of the former Rehe Province. Both Jehol and Rehe are forms of the former Chinese name of the city of Chengde; Jinzhou refers to the State of Jin that formerly occupied part of the diocese.
The diocese lost an important part of its territory in 2018, when the entire city of Chengde was taken out to form the Diocese of Chengde, a suffragan of the Archdiocese of Beijing. Now, only the Liaoning part of the diocese remains, along with a very small part of Hebei.
