Jiagedaqi District, also known as Jagdaqi District, is a district located within the Oroqen Autonomous Banner of Hulunbuir in the Inner Mongolia region of China. While it is physically situated in Inner Mongolia, it serves as the de facto seat of the Daxing'anling Prefecture.
The administrative status of Jiagedaqi is unique due to a jurisdictional arrangement where it falls under the jurisdiction of Daxing'anling Prefecture because there is no suitable location for a seat within the prefecture itself. This specific arrangement is currently disputed by the government of Inner Mongolia.
