Dagestan Nature Reserve (Russian: Дагестанский заповедник) (also Dagestansky) is a Russian 'zapovednik' (strict nature reserve) that protects an area of sand dunes and ridges on the northwest coast of the Caspian Sea in the southeast of European Russia.

[1][2] The Dagestan Reserve sits on the northwest coast of the Caspian Sea, at the mouth of the Kuma River as it empties into Kizlyar Bay.

The reserve covers the low, marshy wetlands of the Kuma delta, as well as the entirety of Kizlyar Bay.

[1] The reserve includes four sectors that are disconnected from the Kizlyar Bay territory: Dagestan is located in the Caspian lowland desert ecoregion.

This climate is characterized by high variation in temperature, both daily and seasonally; with dry winters and cool summers.

During the migrations on the west coast of the Caspian are large numbers of cormorants, grebes, ducks, geese and gulls.
