Yu Zhishan (Chinese: 于芷山; pinyin: Yú Zhǐshān; Hepburn: U Shizan; 1882 – May 1951), was a military officer under the Beiyang Government and the Fengtian clique, subsequently becoming a cabinet minister in Manchukuo.

He returned to Shandong Province as commander of the 30th Army, assisting Chiang Kai-shek in defeating the forces of Yan Xishan in the Central Plains War.

Yu initially supported Zhang Xueliang, who appointed him commander in chief of the military in the 20 prefectures immediately surrounding Shenyang.

Following the Mukden Incident of September 1931, Yu worked with Kan Chaoxi to declare Shenyang independent from the Republic of China, and subsequently cooperated with the Imperial Japanese Army on the Self-Government Guiding Board in the establishment of the state of Manchukuo.

Following the collapse of Manchukuo, he fled to Beijing, where he lived under an assumed name until some point after the establishment of the People’s Republic of China in October 1949.
