Gissar Range is a mountain range in Central Asia, in the western part of the Pamir-Alay system, stretching over 200 km in the general east-west direction across the territory of Tajikistan and Uzbekistan. The Gissar Range (also known as Hissar or Hisor Range) lies south of the Zeravshan Range, extending north of Dushanbe through Tajikistan's Gissar District and reaching Uzbekistan at the north tip of Surkhandarya Province. The highest point in the Gissar Range at 4,643 meters (15,233 ft) is located in Uzbekistan on the border with Tajikistan, just north-west of Dushanbe. Formerly known as Peak of the 22nd Congress of the Communist Party, the Khazret Sultan is also the highest point in all Uzbekistan.
