Wang Yun () (137–192), courtesy name Zishi, was a Chinese politician who lived during the Eastern Han dynasty. He served in the Han government through the reigns of three emperors – Emperor Ling (), Emperor Shao (189) and Emperor Xian (). The highest offices he served in were Manager of the Affairs of the Masters of Writing and Minister over the Masses in the early reign of Emperor Xian. In 192, with help from the general Lü Bu and others, he plotted a successful coup in Chang'an against Dong Zhuo, a tyrannical warlord who controlled the Han central government, and assassinated him. However, later that year, Dong Zhuo's followers staged a counter-coup and seized back control of the central government. Wang Yun, along with his family members, was captured and executed.
