Jiagedaqi District or Jagdaqi District is a district and the de facto seat of Daxing'anling Prefecture in Heilongjiang. Its physical location is in Oroqen Autonomous Banner, Hulunbuir, Inner Mongolia; however, it is de facto under the jurisdiction of Daxing'anling Prefecture due to a lack of a suitable location for a seat in Daxing'anling itself. The government of Inner Mongolia disputes this arrangement.
