Ochre Coloured Pottery culture (OCP) is a 2nd millennium BC Bronze Age culture of the Indo-Gangetic Plain, extending from eastern Punjab to northeastern Rajasthan and western Uttar Pradesh. It is considered a candidate for association with the early Indo-Aryan or Vedic culture. Early specimens of the characteristic ceramics found near Jodhpura, Rajasthan, date from the 3rd millennium (this Jodhpura is located in the district of Jaipur and should not be confused with the city of Jodhpur). Several sites of culture flourish along the banks of Sahibi River and its tributaries such as Krishnavati river and Soti river, all originating from the Aravalli range and flowing from south to north-east direction towards Yamuna before disappearing in Mahendragarh district of Haryana.
