The Orang National Park (Pron: ɒˈræŋ or ɒˈrɑ:ŋ), located on the north bank of the Brahmaputra River in the Darrang and Sonitpur districts of Assam, India, covers an area of 78.81 square kilometres (30.43 sq mi). It was established as a sanctuary in 1985 and declared a national park on 13 April 1999. It is also known as the mini Kaziranga National Park (IUCN site) since the two parks have a similar landscape made up of marshes, streams and grasslands. The park has a rich flora and fauna, including great Indian one-horned rhinoceros, pigmy hog, elephants, wild buffalo and tigers.
