Dehradun (), also spelled Dera Doon, is the capital of Uttarakhand, a state in India. Located in the Garhwal region, it lies 236 kilometres (147 mi) north of India's capital New Delhi and 168 kilometres (104 mi) from Chandigarh. It 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. During the days of British Raj, the official name of the town was Dehra.
