Manas National Park is a national park, Project Tiger reserve, and an elephant reserve in Assam, India. Located in the Himalayan foothills, it borders the Royal Manas National Park in Bhutan. The park is known for its rare and endangered endemic wildlife such as the Assam roofed turtle, hispid hare, golden langur and pygmy hog. Manas is also famous for its population of the wild water buffalo. Because of its exceptional biodiversity, scenery, and variety of habitats, Manas National Park is a biosphere reserve and a UNESCO World Heritage Site.
The name of the park is originated from the Manas River. The Manas river is a major tributary of Brahmaputra River, which passes through the heart of the national park.
The Manas National Park was declared a sanctuary on 1 October 1928 with an area of 360 km2 (140 sq mi). Manas bio reserve was created in 1973.
