Yun Daiying (August 12, 1895 – April 29, 1931) was an early leader of the Chinese Communist Party.

In 1913, Yun Daiying entered the private Zhonghua University in Wuchang, and after graduation in 1918, he stayed there as an instructor.

After Chiang Kai-shek and Wang Jingwei launched a purge against the communists in succession in April and July 1927, he was sent to Jiujiang, where he helped organize the Nanchang Uprising.

In the end of 1928, he started to direct propaganda work of the communist party, creating the periodical Red Flag.

Before his death, Yun Daiying wrote in prison a poem of martyrdom: Having roamed far and wide, I recollect old comrades, Old comrades are immortal regardless of life or death, I've dismissed personal loss, seeing it as negligible, Preserving my heroic bent albeit serving as prisoner.
