Jin Zhun (Chinese: 靳準; c.January 319[1]) was an official and a member of the consort kin of the Xiongnu-led Han-Zhao dynasty of China who briefly usurped the throne in 318.
He then proclaimed himself Heavenly King of Han and nominally submitted to the Eastern Jin dynasty as a vassal.
His forces were subsequently squeezed in by the troops led by Liu Yao and Shi Le, and, facing probable defeat, his followers assassinated him.
Jin Zhun was probably an ethnic Xiongnu, although some sources claim that he was of Han descent.
That same year, Upper Empress Jin was revealed by the official Chen Yuanda as having committed adultery, causing Liu Cong to feel compelled to depose her.
Shi Le, whose headquarters were closer at Xiangguo (襄國, in modern Xingtai, Hebei), quickly arrived near the capital Pingyang (平陽, in modern Linfen, Shanxi), but chose to not engage Jin Zhun immediately.
