The Shangdang Campaign () was a series battles fought between the Communist force under the leadership of Liu Bocheng and the nationalist Yan Xishan’s Kuomintang force. The Campaign lasted from September 10, 1945, through October 12, 1945. Like all other communist victories in the clashes immediately after Japanese's surrender in World War II, the outcome of this campaign altered the course of the peace negotiation held in Chongqing from August 28, 1945 through October 11, 1945, resulting in a more favourable outcome for Mao Zedong.
