Kuai Liang (fl. 190s–200s), courtesy name Zirou, was an adviser to the warlord Liu Biao during the late Eastern Han dynasty of China. He was from Zhonglu County, Nan Commandery, which is located southwest of present-day Xiangyang, Hubei. He had a younger brother, Kuai Yue.
In the 14th-century historical novel Romance of the Three Kingdoms, Kuai Liang comes up with a plan to defeat Sun Jian at the Battle of Xiangyang in 191. He suggests to Huang Zu to retreat and lure Sun Jian to Xianshan (峴山), where Sun Jian is killed by Huang Zu's archers lying in ambush.
