Rangpur is an ancient archaeological site in Surendranagar district near Vanala on Saurashtra peninsula in Gujarat, western India. Lying on the tip between the Gulf of Khambhat and Gulf of Kutch, it belongs to the period of the Indus Valley civilization, and lies to the northwest of the larger site of Lothal. It is the type site for the Rangpur culture, a regional form of the late phase of the Indus Valley Civilization that existed in Gujarat during the 2nd millennium BCE.
