The 1720 Chinese expedition to Tibet or the Chinese conquest of Tibet in 1720 was a military expedition sent by the Qing dynasty to expel the invading forces of the Dzungar Khanate from Tibet and establish Qing rule over the region, which lasted until the empire's fall in 1912.

The Dzungar Khanate, also written as the Zunghar Khanate or Junggar Khanate, was an Inner Asian khanate of Oirat Mongol origin. At its greatest extent, it covered an area from southern Siberia in the north to present-day Kyrgyzstan in the south, and from the Great Wall of China in the east to present-day Kazakhstan in the west. The core of the Dzungar Khanate is today part of northern Xinjiang, also called Dzungaria.
