Outer Northwest China () refers to small portions of territories of the Qing dynasty that were later annexed by the Russian Empire through the Convention of Peking, Treaty of Tarbagatai, Treaty of Saint Petersburg (1881) and other unequal treaties referred by Chinese interpretation. During Qing rule, the territories formed parts of far-Western Xinjiang, Northwestern Outer Mongolia and the entirety of Tannu Uriankhai. Prior to Qing rule, Outer Northwest China was part of the Dzungar Khanate but the region was annexed into the Qing Empire in the aftermath of the Dzungar–Qing Wars.
