Amursana (Mongolian ; ; 172321September 1757) was an 18th-century "taishi" () or prince of the Khoit-Oirat tribe that ruled over parts of Dzungaria and Altishahr in present-day northwest China. Known as the last great Oirat hero, Amursana was the last of the Dzungar rulers. The defeat of his rebel forces by Qing dynasty Chinese armies in the late 1750s signaled the final extinction of Mongol influence and power in Inner Asia, ensured the incorporation of Mongol territory into the Qing Chinese Empire, and brought about the Dzungar genocide, the Qing Emperor's "final solution" to China's northwest frontier problems.
