Wang Yun () (137–4 July 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. In the 14th-century historical novel Romance of the Three Kingdoms, Wang Yun was the adoptive father of the fictional maiden Diaochan, whom he used to stir up conflict between Lü Bu and Dong Zhuo, causing the former to betray and assassinate the latter.

Wang Yun himself was an official at the age of 19, and became the Inspector of Yu Province (). However, later he failed in the power struggle with the eunuch Zhang Rang. He had to abandon his position and hide himself in the countryside. After the death of Zhang Rang, the general He Jin came into power, and Wang Yun was promoted to the Gentleman of the Household and later to the Intendant of Henan (). In 190, the capital Luoyang fell into chaos following the death of He Jin and a bloody clash between the powerful Ten Attendants and government officials. Dong Zhuo, a warlord from Liang Province () managed to take control of the situation and eventually placed in the throne a puppet emperor whom he held in his power. At the time, Wang Yun held the positions of the Minister over the Masses (), replacing Yang Biao, and the Prefect of the Masters of Writing (). Dong Zhuo's subsequent tyrannical and cruel behaviour aroused the wrath of many. Wang Yun then colluded with several other officials in a plot to assassinate Dong Zhuo.
