Zhao Yun (died 229), was a military general who lived during the late Eastern Han dynasty and early Three Kingdoms period of China. Originally a subordinate of the northern warlord Gongsun Zan, Zhao Yun later came to serve another warlord, Liu Bei, and had since accompanied him on most of his military exploits, from the Battle of Changban (208) to the Hanzhong Campaign (217–219). He continued serving in the state of Shu Han – founded by Liu Bei in 221 – in the Three Kingdoms period and participated in the first of the Northern Expeditions until his death in 229. While many facts about Zhao Yun’s life remain unclear due to limited information in historical sources, some aspects and activities in his life have been dramatised or exaggerated in folklore and fiction. In the 14th-century historical novel Romance of the Three Kingdoms, he was lauded as a member of the Five Tiger Generals under Liu Bei. Zhao Yun’s original biography in the Records of the Three Kingdoms (Sanguozhi), written by Chen Shou in the third century, is only 346 Chinese characters long. In the fifth century, Pei Songzhi added annotations from the Zhao Yun Biezhuan to Zhao Yun’s biography in the Sanguozhi, providing a relatively clear, though still incomplete picture of Zhao Yun’s life.
