Sun Huan (195-234), courtesy name Jiming, was a military general of the state of Eastern Wu during the Three Kingdoms period.

In 212, his elder brother Jiao was promoted to general and left in charge of Xiakou[a] in Jiangxia, replacing the general Cheng Pu (程普) who had organised the defences of this territory after it was transferred to Liu Bei, two years earlier.

In 226, despite Sun Quan's unsuccessful campaign to seize northern Jiangxia, he captured three Wei generals at Shiyang and was then enfeoffed for his achievements.

[4] He died in 234 and was well remembered by the people of Wu, who praised him for his contributions to promoting scholarship in Jiangxia.
