The Dzungarian Alatau is a mountain range that lies on the boundary of the Dzungaria region of China and the Zhetysu region of Kazakhstan. It has a length of 450 km (280 mi) and a maximum elevation of 4,464 m (14,646 ft).

Dzungaria, also known as Northern Xinjiang or Beijiang, is a geographical subregion in Northwest China that corresponds to the northern half of Xinjiang. Bound by the Altai Mountains to the north and the Tian Shan mountain range to the south, Dzungaria covers approximately 777,000 km2 (300,000 sq mi), and borders Kazakhstan to the west and Mongolia to the east. In contexts prior to the mid-18th century Dzungar genocide, the term "Dzungaria" could cover a wider area, coterminous with the Oirat-led Dzungar Khanate.
