Zhang Ren (died 213) was a general serving under the warlord Liu Zhang during the late Han Dynasty period of Chinese history.
In Luo Guanzhong's historical novel Romance of the Three Kingdoms, Zhang Ren served under Liu Zhang. During Liu Bei's invasion of Yi Province, Zhang planned an ambush at the Valley of the Fallen Phoenix intended for Liu Bei, but Liu Bei's advisor Pang Tong was killed instead. After Liu Bei seized control of Yi Province from Liu Zhang, Zhang Ren was captured and Liu Bei offered him a chance to serve him. Zhang refused, saying, "A loyal subject cannot serve two lords. I decline." He was then executed by Liu Bei and buried with full honours for his loyalty to Liu Zhang.
