Dehradun (), also known as Dera Doon, is the winter capital and the most populated city of the Indian state of Uttarakhand. It is the administrative headquarter of the eponymous district and the city is governed by the Dehradun Municipal Corporation. Part of the Garhwal region, it lies along National Highway 7 with the distance of north of India's capital New Delhi and is well-connected with a rail line (Dehradun railway station) and the airport (Jolly Grant Airport). Dehradun is one of the "Counter Magnets" of the National Capital Region (NCR) being developed as an alternative centre of growth to help ease the migration and population explosion in the Delhi metropolitan area and to establish a smart city at Dehradun.
