200s–210s) was a government official and minor warlord who lived during the late Eastern Han dynasty of China.
Little is recorded about Zhao Fan in history, except that he was already serving as the Administrator (太守) of Guiyang Commandery (桂陽郡; around present-day Chenzhou, Hunan) around 208 and 209.
In 209, the warlord Liu Bei led his forces to conquer the four commanderies in southern Jing Province: Wuling, Lingling, Changsha and Guiyang.
Zhao Fan had a widowed elder sister-in-law, Lady Fan (樊氏), who was known for her beauty, and he wanted to arrange for a marriage between her and Zhao Yun.
In the novel, however, Zhao Yun rejects the offer because he has become sworn brothers with Zhao Fan, so it is inappropriate for him to marry his sworn brother's sister-in-law.
