Jin Zhun (; died 318) 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. Jin Zhun staged a coup d'état against the Han Zhao emperor and his son-in-law Liu Can (Emperor Yin) and then massacred the Liu imperial family. 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. Liu Yao then succeeded Jin Zhun to the Han Zhao throne.

As years went by, Jin Zhun became closely associated with the Liu Can and several eunuchs and servants trusted by Liu Cong and Liu Can, including Wang Chen (王沈), Xuan Huai (宣懷), and Guo Yi (郭漪). Jin and Guo were instrumental in persuading Liu Can that his uncle, Liu Ai (劉乂) the crown prince was conspiring against him and his father, and subsequently participated heavily in Liu Can's plot to have his uncle falsely accused of treason and removed as crown prince in 317. Jin also assassinated the former Crown Prince Ai, on Liu Can's orders. Liu Can became crown prince, and Princess Jin became crown princess. Coup against Liu Can After Liu Cong died in summer 318, Liu Can succeeded to the throne, and proceeded to spend day and night committing adultery with his father's four surviving empresses—one of which was Jin Zhun's daughter Jin Yuehua.
