The Baikal Mountains or Baikal Range (Russian: Байкальский хребет, Baykalskiy khrebet; Buryat: Байгалай дабаан, Baigalai dabaan) are a mountain range that rises steeply over the northwestern shore of Lake Baikal in southern Siberia, Russia.

[1] The highest peak in the range is 2,572 m high Mount Chersky, named after Russian explorer Ivan Chersky.

[2] The Baikal Mountains are connected with the Primorsky Range to the south, which also stretches along the lakeshore.

The Akitkan Range, part of the North Baikal Highlands, is a northern extension of the mountain chain.

[3] The mountain slopes near Lake Baikal are densely wooded with grey alder, Eurasian aspen, downy birch, Siberian larch, Siberian fir, Scots pine, and Siberian spruce.
