The Kungey Alatau (Kyrgyz: Күңгөй Ала-Тоо, Küngöy Ala-Too; Kazakh: Күнгей Алатау, Küngei Alataw), also spelled Kungoy Ala-Too, and Kungey Alataw, is a mountain range, which forms the northern Tien Shan with Zailiyskiy Alatau.

The word "Alatau" or "Ala-too" means "variegated mountains", a designation indicating a pronounced high-altitude zone of mountains, partly white due to snow, partly dark on snowless areas.

The word "Kungey" or "Kyungei" means "the side (of the mountain) facing to the South".

The range begins in the west in the area of the Boom Gorge of the Chu River, where it adjoins the Kyrgyz Ala-Too.

The largest river of the southern slope of the Kungey Alatau, Chon-Ak-Suu, which flows into Issyk-Kul, begins at this point and flows in an easterly direction, so that the northern slope of its valley is the main ridge of the Kungey Alatau, and the southern ridge of the Kumbel.

At low altitudes, there is a forest (mainly Tien Shan spruce), and then from 2,800 to 3,600 meters (9,200 to 11,800 ft) there is a subalpine zone, even higher — glaciers.
