Salair Ridge (pronounced sah-lah-EER; Russian: Салаирский кряж) is an eroded plateau-type highland in the Southwestern Siberia, Russia, particularly in Altai Krai, Kemerovo and Novosibirsk Oblast. It is a natural continuation of Altai Mountains and separates the Kuznetsk Depression from the Ob River Plain to the southwest. See Geography of South-Central Siberia. Its main ridge is nearly parallel to that of Kuznetsk Alatau.
