Tarata is a district of Tarata, a province of the department of Tacna, Peru. Its capital is Tarata.
Following the 1883 Treaty of Ancón, Chile established a province to administer its newly acquired territory south of the Sama River. Due to differing interpretations of the rivercourse, the area's administration by Chile proved controversial. Tarata was made a sub-delegation of Tacna, with its jurisdiction including the former Peruvian districts of Tarata, Tarucachi and Estique. The sub-delegation was elevated to department from 1911 to 1921, after which it was disestablished and handed over to Peru in 1925.
The Barroso mountain range traverses the district. Some of the highest mountains of the district are listed below:
