Ulan-Burgas (Russian: Улан-Бургасы; Buryat: Улаан бургааhан, from улаан - "red", and бургааһан, "small birch" or "shrub"),[1] is a mountain range in Buryatia, Russia.

It rises east of the Baikal Lake, stretching for 200 kilometres (120 mi) from southwest to northeast between the valley of the Selenga River to the Vitim Plateau.

The highest peak is Khurkhag at 2,033 m (6,670 ft) located in the central part.

[4] At one end of the range is the valley of the Turka River that flows into Lake Baikal and at the other end the Kurba, a right tributary of the Uda from the Selenga River basin.

The higher elevations are topped by "golets" type bare summits.
