Wang Yun (137–192) is a Minister over the Masses under Emperor Xian during the late Eastern Han Dynasty of China.

During Wang Yun's time, the emperors are mere puppets under the power of eunuchs and warlords.

In 192, Wang Yun plots and successfully stages Lü Bu's assassination of Dong Zhuo, the tyrannical warlord in power.

However, Dong Zhuo's former subjects soon lead a coup, in which Wang Yun is executed, along with most of his family.

In the historical novel Romance of the Three Kingdoms, Wang Yun was the adoptive father of the possibly fictional Diaochan, whom he used to seduce both Lü Bu and Dong Zhuo.

The subsequent rift that arose between the foster father and son eventually saw the death of Dong Zhuo by the hands of Lü Bu.
