Dong Zhuo (died May 22, 192) is a politician and warlord during the late Han Dynasty period of Chinese history.

He seizes control of the capital city Luoyang in 189 when it is in a state of turmoil following the death of Emperor Ling and a clash between the eunuch faction and some court officials led by General-In-Chief He Jin.

Dong Zhuo subsequently deposes Emperor Shao and instates Emperor Xian.

Dong Zhuo rises to power in the Imperial Court and rules the nation with tyranny and cruelty for a brief period of time.

The following year, a coalition of regional officials and warlords launches a punitive campaign against Dong, forcing him to move the capital city to Chang'an.

Dong Zhuo is assassinated in 192 by his foster son Lü Bu as part of a plot orchestrated by Interior Minister Wang Yun.
