Liu Dai (died 192), courtesy name Gongshan, was a Chinese politician who lived during the late Eastern Han dynasty of China.
Liu Dai was from Mouping County (牟平縣), Donglai Commandery (東萊郡), which is in present-day Muping District, Yantai, Shandong.
Gongsun Zan said to Fan Fang, "If Liu Dai does not drive away Yuan Shao's family members, you will lead your men back to our territory.
Liu Dai ignored Bao Xin and proceeded to attack the Yellow Turbans, and was defeated and killed in battle.
As his achievements increased, Liu Dai became more overconfident and he refused to listen to Bao Xin, which resulted in their deaths.
