Kuznetsk Alatau Nature Reserve (Russian: Кузнецкий Алатау заповедник) is a Russian 'zapovednik' (strict nature reserve) on the Kuznetsk Alatau, a mountain ridge in the Altai-Sayan mountain region in southwestern Siberia.

The Kuznetsk Alatau consists of several ranges of medium height, between which there are river valleys.

The Kuznetsk Alatau Reserve has a terrain that organized on a series of three relatively flat levels ascending a mountain ridge cut with river valleys.

[2] 5-8% of the reserve is alpine, with terrain typical of glacial origin: troughs, cirque lakes, etc.

Below the alpine belt, 1600–1250 meters, is a region of flattened land with scattered blocks of igneous rocks and tundra landscapes with dwarf willows, birches, sedges, mosses, lichens and some mountain bogs.

Through this are cut river valleys through layers of limestone and schists with rocky outcrops.

There are three 'ecotourist' river rafting routes in the reserve, however, that are made available to guided tours for the public.
