The state is bordered by Pakistan to the west, Gujarat to the southwest, Madhya Pradesh to the southeast, Uttar Pradesh and Haryana to the northeast and Punjab to the north. Rajasthan covers 10.4% of India, an area of 342,269 square kilometres (132,151 sq mi).

Jaipur is the capital and the largest city of the state. Geographical features include the Thar Desert along north-western Rajasthan and the termination of the Ghaggar River near the archaeological ruins at Kalibanga of the Indus Valley Civilization, which are the oldest in the Indian subcontinent discovered so far.
