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.

A khanate or khaganate is a type of historic polity ruled by a khan, khagan, khatun, or khanum. Khanates were typically nomadic Turkic, Mongol and Tatar societies located on the Eurasian Steppe, politically equivalent in status to kinship-based chiefdoms and feudal monarchies. Khanates and khaganates were organised tribally, where leaders gained power on the support and loyalty of their warrior subjects, gaining tribute from subordinates as realm funding. In comparison to a khanate, a khaganate, the realm of a khagan, was a large nomadic state maintaining subjugation over numerous smaller khanates. The title of khagan, translating as "Khan of the Khans", roughly corresponds in status to that of an emperor.
