Zhang Gui (張瓌) (d. February 10, 888[1][2]) was a warlord late in the Chinese Tang dynasty who controlled Jingnan Circuit (荊南, headquartered in modern Jingzhou, Hubei) from 885 to 888.
[4] In any case, Zhang became an officer at Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu), but later rebelled against the military governor (Jiedushi) Gao Pian.
[3] In 885, Chen Ru the military governor of Jingnan was faced with repeated raids against the circuit by Lei Man the prefect of Lang Prefecture (朗州, in modern Changde, Hunan).
He invited Zhang and another former Huainan officer, Han Shide (韓師德), who had also rebelled against Gao and taken over Yue Prefecture (岳州, in modern Yueyang, Hunan) as its prefect, to serve under him and attack Lei.
Zhao left his officer Wang Jianzhao in control of Jingnan and withdrew back to his base at Shannan East Circuit (山南東道, headquartered in modern Xiangyang, Hubei).
