Orang National Park is a national park in India located on the northern bank of the Brahmaputra River in the Darrang and Sonitpur districts of Assam. It covers an area of 79.28 km2 (30.61 sq mi). It was established as a sanctuary in 1985 and declared a national park on 13 April 1999. It is rich in flora and fauna, including great Indian rhinoceros, pygmy hog, Asian elephant, wild water buffalo and the Bengal tiger. It is the only stronghold of the rhinoceros on the north bank of the Brahmaputra.
The park has a chequered history of habitation. Up to 1900, it was inhabited by the local tribes. On account of an epidemic disease, the tribal population abandoned the area. The park was renamed the Rajiv Gandhi Wildlife Sanctuary in 1992; however, this action had to be reversed due to public pressure against the renaming. Finally, the sanctuary was declared a National Park in 1999.
