Assam pronunciation (help·info) (Assamese: অসম Ôxôm [ɔxɔm]) is a northeastern state of India with its capital at Dispur located in the city of Guwahati. Located south of the eastern Himalayas, Assam comprises the Brahmaputra and the Barak river valleys along with the Karbi Anglong and the North Cachar Hills with an area of 30,285 square miles (78,438 km²). Assam is surrounded by six of the other Seven Sister States: Arunachal Pradesh, Nagaland, Manipur, Mizoram, Tripura and Meghalaya. These states are connected to the rest of India via a narrow strip in West Bengal called the Siliguri Corridor or "Chicken's Neck". Assam also shares international borders with Bhutan and Bangladesh; and cultures, peoples and climate with South-East Asia – important elements in India’s Look East policy.

Assam became a part of India after the British occupied the region following the First Anglo-Burmese War of 1824-1826. It is known for Assam tea, large and old petroleum resources, Assam silk and for its rich biodiversity. Assam has successfully conserved the one-horned Indian rhinoceros from near extinction, along with the tiger and numerous species of birds, and it provides one of the last wild habitats for the Asian elephant. It is becoming an increasingly popular destination for wildlife tourism, and Kaziranga and Manas are both World Heritage Sites. Assam was also known for its Sal tree forests and forest products, much depleted now. A land of high rainfall, Assam is endowed with lush greenery and the mighty river Brahmaputra, whose tributaries and oxbow lakes provide the region with a unique hydro-geomorphic and aesthetic environment.
