The Batak Reservoir (Bulgarian: язовир Батак) is located in the Rhodope Mountains and is the third largest in Bulgaria.

It attracts many tourists and fishermen, and the resort Tsigov Chark was built on its shore.

The lake is situated around 8 km away from the historic town of Batak from which it took its name.

There is a hydro-electric power plant constructed in Batak that is, among other sources, powered by water from the Batak reservoir.
