Xiahou Dun (died 13 June 220) courtesy name Yuanrang, was a military general serving under the warlord Cao Cao during the late Eastern Han dynasty of China. He served for a few months under Cao Cao's successor, Cao Pi, before his death. As one of Cao Cao's most trusted generals, Xiahou Dun aided the warlord in his campaigns against Lü Bu, Liu Bei, Sun Quan and others.

Xiahou Dun lost his left eye when he was a hit by a stray arrow during a battle against Lü Bu in the late 190s, and subsequently became known among the rank and file as "Blind Xiahou". His image as a one-eyed warrior was popularised by the 14th-century historical novel Romance of the Three Kingdoms, in which he yanked the arrow out of his eye and devoured his eyeball.
