Yu Qiangsheng (; 1940–1990s?) was a spy chief of the People's Republic of China who defected to the United States in 1985. The information he provided led to the arrest and suicide of the top Chinese spy Larry Wu-Tai Chin. He was a son of Communist revolutionaries Huang Jing (Yu Qiwei) and Fan Jin, and the elder brother of Yu Zhengsheng, the fourth highest-ranking leader of the Communist Party of China since November 2012.
