Tsimlyansk Reservoir or Tsimlyanskoye Reservoir (Russian: Цимля́нское водохрани́лище) is an artificial lake on the Don River in the territories of Rostov and Volgograd Oblasts at 47°50′N 42°50′E / 47.833°N 42.833°E / 47.833; 42.833. Completed in 1952, the reservoir is one of the largest in Russia, providing power (Tsimlyansk Hydroelectric Station () ) and irrigation to the Rostov and Volgograd regions. Crops grown around the lake include wheat, rice, cotton, maize, alfalfa, fruit, grapes, and vegetables.

The reservoir, together with the Volga-Don Canal and the lower course of the Don, provides an important waterway between the Volga River / Caspian Sea basin and the Sea of Azov. The Tsimlyansk Dam also provides flood control for the lower Don River basin.
