Liu Xian (Chinese: 劉顯; died 352) was a military general of the Later Zhao dynasty and ruler during the Sixteen Kingdoms period. During the Ran Wei–Later Zhao War, he defected to Ran Wei and assassinated the Zhao emperor, Shi Zhi, thus ending the Later Zhao. However, he then betrayed Wei and declared himself emperor in Zhao's capital, Xiangguo (襄國, in modern Xingtai, Hebei), but was eventually defeated and killed in 352.
