The Selenga Highlands (Russian: Селенгинское среднегорье) are a mountainous area in Buryatia and the southwestern end of Zabaykalsky Krai, Russia.

In the southeast they adjoin the Khentei-Daur Highlands and to the south lies the Mongolia–Russia border.

[2] The Selenga Highlands include low to middle height mountain ranges with elevations ranging from 800 metres (2,600 ft) to 2,000 metres (6,600 ft) above sea level, generally oriented in a northeast and ENE direction.

In the Selenga Highlands some areas between ranges are occupied by significant depressions.

Of the rare plant species, the Siberian apricot, listed in the Red Book of Buryatia, deserves mention.
