Amursana (1723 – 21 September 1757) is an eighteenh-century taishi  or prince of the Khoit-Oirat tribe that rules over parts of Dzungaria and Altishahr in present-day northwest China.

Known as the last great Oirat hero, Amursana is the last of the Dzungar rulers.

The defeat of his rebel forces by Qing armies in the late 1750s signals the final extinction of Mongol influence and power in Inner Asia, ensures the incorporation of Mongol territory into the Qing Empire, and brings about the Dzungar genocide, the Qing Emperor's "final solution" to China's northwest frontier problems.
