Wang Dun (266–324), courtesy name Chuzhong, is a Jin Dynasty (265-420) general and later warlord.

Having brought Emperor Yuan (Sima Rui) to submission with his military force, Wang Dun has paramount authorities.

However, although he later appears to intend to seize the Jin throne by force, he grows ill in 324.

He later dies as his forces are being repelled by Emperor Ming.
