The Kalar Range (Russian: Каларский хребет, romanized: Kalarskiy khrebet) is a mountain range in Zabaykalsky Krai and the NW end of Amur Oblast, Russian Federation.

[4] Located in a desolate area, the Kalar Range was first described and roughly put on the map in 1857 by A.F.

Usoltsev, Lieutenant of the Corps of Military Topographers of the Russian Imperial Army.

It stretches from WSW to ENE for roughly 350 km (220 mi) from the Vitim river valley to the Olyokma, both right tributaries of the Lena.

While peaks in the western part are generally flat-topped, the eastern end has a more marked alpine relief.
