Gibbon Wildlife Sanctuary is located in the south bank of the Brahmaputra river near Jorhat, Assam and is the only wildlife Sanctuary named after a non-human primate.

Out of 15 species of primates found in India, 7 species are found in Gibbon Wildlife Sanctuary. The North Esstern of India has 9 primate species. The evergreen and semi-evergreen nature of the forest has made it ideal home for the primates. The area of the wildlife sanctury is about 21 km²

This habitat is home to the following animals:
Hoolock Gibbon (Bunipithecus hoolock), Capped Langur (Presbytis pileatus), Pig-tailed Macaque (Macaca nemestrina), Stump-tailed Macaque (Macaca arctoides), Assamese Macaque (Macaca assamensis), Asian Elephant (Elephas maximus), Tiger (Panthera tigris)and leopard (Panthera pardus).

However, Conservation of Hoolock Gibbon (Bunipithecus hoolock) and Asian Elephant (Elephas maximus) have been identified as the main species for this project. It is a important protected area in Indian for conservation of primate diversity.

A program under the title "Conservation of Hoolock Gibbon through Education, Awareness and Socio-economic development of the fringe area community in Gibbon Wild Life Sanctuary, Assam, India" was launched. The program was supported by US Fish and Wildlife Service.

A major achievement of this project is the inauguration of the Gibbon Conservation Centre. The Forest Department has allotted a building of 86 m² area for developing a permanent set up for carrying out conservation and research-based work in Gibbon wildlife sanctuary in future.
