Fan Ben (Chinese: 范賁; died 349), was a politician and emperor of the Cheng-Han dynasty during the Sixteen Kingdoms. He was the son of Fan Changsheng, and after the fall Cheng-Han to the Jin dynasty (266–420) in 347, he led a restoration of the state, briefly ruling over it before his defeat and death in 349. Despite proclaiming himself emperor, most, if not all, historians do not acknowledge his reign and consider Li Shi as the last true ruler of Cheng-Han.
