Dospat Reservoir (Bulgarian: язовир Доспат) is situated in the western part of the Rhodope Mountains, Bulgaria.

At 1,200 m (3,900 ft) above the sea level, it is one of the highest dams in Bulgaria in terms of altitude, and, with its 22 km2 (8.5 sq mi) of water area, the second largest in capacity.

The terrain is hilly, with meadows and arable land available, used for grazing, potato growing and other agricultural activities.

In the surrounding areas there are a number of other large dams, including Vacha, Golyam Beglik, Batak and Shiroka Polyana.

Along the south bank there runs a rough dirt track from Sarnitsa to Dospat but this is only used to access the holiday spots.
