Dibang Wildlife Sanctuary, Wildlife sanctuary in Dibang Valley, India

Dibang Wildlife Sanctuary lies in the Upper Dibang Valley district of Arunachal Pradesh and covers 4,149 km2, making it one of the eight wildlife sanctuaries of the state. Its slopes hold Mishmi takin, red goral, musk deer, red panda, Asiatic black bear, Gongshan muntjac, and occasionally tiger, while Sclater's monal and Blyth's tragopan occur among the birds. The Mishmi Hills giant flying squirrel (Petaurista mishmiensis) was described from the sanctuary's edge.

The area became a protected reserve in 1992 when the government established it to safeguard endangered animal species and natural habitats in the eastern Himalayas. This action was part of broader efforts to secure the biodiversity of this mountainous region.

The Idu Mishmi people who live near the sanctuary practice forest stewardship methods learned from their ancestors. Their approach to the land reflects a deep connection between their community and the surrounding woods.

The sanctuary lies in the Upper Dibang Valley district and is managed by the Arunachal Pradesh Department of Environment and Forests. It falls fully or partly within the Dihang-Dibang Biosphere Reserve, so access follows reserve rules. Plan around the reserve's conditions rather than marked trails, since the terrain is remote mountain country.

A new species of flying squirrel, the Mishmi Hills giant flying squirrel (Petaurista mishmiensis), was recently discovered at the edge of this sanctuary. The sanctuary also lies fully or partly within the Dihang-Dibang Biosphere Reserve.
