Kvarkush (Russian: Кваркуш) is a mountain range in North Ural, in Perm Krai, Russia.

Its highland swamps are the source of many rivers and streams.

The highest point is Mount Vogulsky Kamen at 1,066 metres (3,497 ft).

The name of the mountain range is derived from the Mansi word kvar-kush that literally means "naked (unforested) Ural".

Perhaps, this name was given because there are no forests at elevations of more than 1,000 metres (3,300 ft) and the landscape consists of mountainous tundra and stone deposits.
