Zhao Lei (died 220), style name Kansui (闞穗), was a military officer serving under the warlord Liu Bei during the late Han Dynasty period of Chinese history.

Biography
Zhao Lei was a controller (都督) under Guan Yu. In 220, Zhao Lei was captured by Sun Quan's general Ma Zhong after Lü Meng's invasion of Jing Province, along with Guan Yu and Guan Ping.

In fiction
In Chapter 73 of Luo Guanzhong's novel Romance of the Three Kingdoms, when Guan Yu was attacking Fancheng, Wang Fu recommended that Zhao Lei be left to defend Jingzhou, but Guan Yu instead appointed Zhao as a supply officer.

Later, when Guan was trapped in Maicheng, Zhao proposed a plan and followed Guan in an attempt to break out of the siege. They were ambushed by Sun Quan's forces and Zhao was killed in action.
