The North Shanxi Autonomous Government (also known as the Jinbei Autonomous Government; Chinese: 晋北自治政府; pinyin: Jìnběi zìzhì zhèngfǔ; Wade–Giles: Chin4-pei3 tzu4-chih4 cheng4-fu3; Hepburn: Susumu kita jichi seifu) was an administratively autonomous component of Mengjiang from its creation in 1937 to its complete merger into Mengjiang in 1939. Following the Japanese invasion of China in July 1937, regional governments were established in Japanese-occupied territories. After Operation Chahar in September 1937, which extended Japanese control to northern Shanxi region, more formal control of the area was established through the creation of the North Shanxi Autonomous Government, as well as the South Chahar Autonomous Government to the east of Shanxi.
