190–219), courtesy name Jiyu, was a Chinese politician and warlord who served as provincial governor who lived in the late Eastern Han dynasty of China.

Liu Zhang is often considered an incapable leader but is noted to have been the original lord of some of Shu Han's most famous generals and officials such as Fa Zheng, Meng Da, Zhang Ni, Liu Ba, Huang Quan, Wu Yi, Li Yan, Dong He and others.

Due to Liu Zhang's laxity, his laws and authority was too feeble to control the clans and officials of Yi,[8] while Liu Yan's former army composed of refugees of Nanyang and regions around Chang'an, named the Dongzhou military (東州兵), subjugated and bullied the local people.

Due to the resentment of the people of Yi, Zhao Wei then established relations with the eminent families of Jing Province, intending to raise arms against Liu Zhang.

Although generals such as Zhang Ren fought hard to defend their master, Liu Bei's forces had the upper hand, and by 214 they had surrounded Yi Province's capital, Chengdu.

In the winter of 219-220, however, forces led by Lü Meng, a subordinate of Sun Quan, captured Liu Bei's general Guan Yu and executed him, seizing Jing Province.

His eldest son, Liu Xun (劉循), served as a General of the Household of Equipage in the Shu Han state during the Three Kingdoms period.

In popular accounts of the period, such as the 14th-century historical novel Romance of the Three Kingdoms, Liu Zhang is portrayed as a foolish and incapable ruler.

In Chen Shou's Records of the Three Kingdoms, contemporary accounts evaluate Liu Zhang as being benevolent and unambitious but weak-willed and ineffectual ruler, who lacked the authority and decisiveness to sufficiently control and administer the state.
