Dzungaria (also spelled Zungharia) is a geographical region in northwest China corresponding to the northern half of Xinjiang, also known as Beijiang . Bounded by the Tian Shan mountain range to the south and the Altai Mountains to the north, it covers approximately , extending into western Mongolia and eastern Kazakhstan. Formerly the term could cover a wider area, conterminous with the Dzungar Khanate, a separatist state led by the native Oirats in the 18th century which was based in the area.
Although geographically, historically, and ethnically distinct from the Turkic-speaking Tarim Basin area, the Qing dynasty and subsequent Chinese governments integrated both areas into one province, Xinjiang. As the center of Xinjiang's heavy industry, generator of most of Xinjiang's GDP, as well as containing its political capital Ürümqi ("beautiful pasture" in Mongolian), northern Xinjiang continues to attract intraprovincial and interprovincial migration to its cities. In comparison to southern Xinjiang (Nanjiang, or the Tarim Basin), Dzungaria is relatively well-integrated with the rest of China by rail and trade links.
