Lei Man (雷滿) (died 901), courtesy name Bingren (秉仁), was a warlord late in the Chinese Tang dynasty, who seized control of Lang Prefecture (朗州, in modern Changde, Hunan) in 881 and controlled it and the surrounding region (which was made into Wuzhen Circuit (武貞)) to accommodate him, who was made military governor (jiedushi) until his death in 901.
It is not known when Lei Man was born, but it is known that he was of non-Han extraction, whose people lived in caves in the Wuling (武陵, in modern Changde, Hunan) region, in Lang Prefecture.
With the Tang imperial government then battling the major agrarian rebel Huang Chao, then-reigning Emperor Xizong made Lei the acting prefect.
From this point on, Lei, in control of Lang Prefecture, would make periodic pillages, three or four times a year, against Jingnan's capital Jiangling Municipality.
