Parwan is a province in Afghanistan. It is in the Shomali Plain north-west of Kabul Province, and it is mainly an agricultural region. Parwan's capital is Charikar. The Salang Tunnel provides the only year-round route from Kabul to the northern provinces and thence to Uzbekistan, Tajikistan, and Turkmenistan. Divided into ten districts, Parwan's population is less than one million. The main ethnic groups are Pashtuns and Tajiks.
Parwan is mountainous, with the Kott-i-Baba Range in the southwest, the Panjshir Range in the north, and the Paghman Range in the southeast. Two main rivers cross the province: the Ghowr Band River and the Panjshir River. Crops are grown along the fertile river valleys including the Shomali Plain, and livestock are raised throughout the province. Mountains in the high-altitude Ghorband and Shinwari Districts are covered with snow year-round.
