or Pishin, a district of Baluchistan. Area 2717 sq. m. Pop. (1901), 50,200. It consists of a large plain surrounded on three sides by hills, which formerly belonged to Afghanistan but was ceded to the British by the treaty of Gandamak in 1879. This plain is of considerable strategic importance, as it forms the focus of a great number of routes leading from Sind and the Punjab frontier districts to Kandahar, and is intersected by the Sind-Peshin railway. The agricultural wealth of Peshin, and consequently its revenues, have increased greatly under British administration.
