Chen Yun () (1905 – April 10, 1995) was one of the most influential leaders of the People's Republic of China.

A native of Qingpu (now part of Shanghai), he worked underground as a union organizer in the late 1920s, participated in the Long March, and served on the Central Committee from 1931 to 1987. He was also active in the field of economics, despite receiving no formal education after elementary school.

Chen Yun's position as one of the top Chinese leaders span almost to its entirety. He was one of the Big Five in Communist China along with Mao Zedong, Liu Shaoqi, Zhou Enlai, and Zhu De. A Politburo Standing Committee member for decades, he was one of the Vice-Chairs to the Central Committee until this position was abolished, and from 1987 to 1992 headed the party's Central Advisory Committee, until it was abolished. He is noted for the concept of a "bird-cage economy".

He was considered to be one of the Eight Immortals of Communist China.
