Dihing or Burhi Dihing is a large tributary, about 380 kilometres (240 mi) long,[1] of the Brahmaputra River in Upper Assam in northeastern India. The river originates at 2,375 metres (7,792 ft) above sea level in the Eastern Himalayas (the Patkai Hills)[1] in Arunachal Pradesh and flows through Tinsukia (Tinicukeeya) and Dibrugarh Districts in Assam to its confluence with the Brahmaputra at Dihingmukh. Its watershed covers about 6,000 square kilometres (2,300 sq mi).[1] The Dihing has created number of oxbow lakes in the area.

The Disam is a tributary of the Dihing in its southern bank. The Joy-Dihing Rainforest, numerous petroleum fields, wet-paddy fields, bamboo orchards and tea gardens provide a unique landscape along its course. Ledo, Margherita, Digboi, Duliajan and Naharkatia (Nahorkotiya) are the small towns in its valley. Dihing is the one of the most important contributors to the Brahmaputra River. The plains of the Dihing Valley has a rich variety of flora and fauna. The Betel nuts are produced most in the areas of the Dihing Plains.
