Assam is a state in northeastern India, south of the eastern Himalayas along the Brahmaputra and Barak Valley. Assam covers an area of . The state is bordered by Bhutan and the state of Arunachal Pradesh to the north; Nagaland and Manipur to the east; Meghalaya, Tripura, Mizoram, and Bangladesh to the south; and West Bengal to the west via the Siliguri Corridor, a strip of land which connects the state to the rest of India. 

Assam is known for Assam tea and Assam silk. The first oil well in Asia was drilled here. The state has conserved the one-horned Indian rhinoceros from near extinction, along with the wild water buffalo, pygmy hog, tiger and various species of Asiatic birds. It provides one of the last wild habitats for the Asian elephant. The Assamese economy is aided by wildlife tourism to Kaziranga National Park and Manas National Park which are World Heritage Sites. Sal tree forests are found in the state which, as a result of abundant rainfall, looks green all year round. Assam receives more rainfall compared to most parts of India. This rain feeds the Brahmaputra River, whose tributaries and oxbow lakes provide the region with a hydro-geomorphic environment.
