Kuai Liang, courtesy name Zirou (子柔), was an advisor to the warlord Liu Biao in the late Eastern Han Dynasty. He was a native of Zhonglu, Nan Commandery (present-day Nanzhang County, Hubei). He had a younger brother, Kuai Yue.
In Luo Guanzhong's historical novel Romance of the Three Kingdoms, Kuai Liang was the one who came up with a plan to defeat Sun Jian at the Battle of Xiangyang in 191. He suggested to Huang Zu to retreat and lure Sun Jian to Mount Xian (峴山), where Sun Jian was killed by Huang Zu's archers lying in ambush.
