Morigaon district (IPA: [mʌrɪˈgãʊ]) is an administrative district in the state of Assam in India. The district headquarters is located at Morigaon. The ancient place of occult Mayong is located in this district as well as Pobitora Wildlife Sanctuary.


The history of Morigaon is obscure. One famous traditional ruler of the region was Arimatta whose history is shrouded in mystery. After Arimattas's death, Jongal Balahu (A Great Tiwa King), his son ruled over the region. Jongal Balahu was ultimately killed by the Kacharis with a bamboo spear near Kajalimukh.

The legend further goes on to say that Jongal Balahu to escape his pursuers, submerged himself in Kollong river and emerge at Raha to quench his thirst and again dived here to emerge at Jagi. From this incident were derived the names of present-day Raha and Jagi.

The writing of Bhim Singh throws some light on the history of present Morigaon town and its adjoining areas. This region was ruled independently by six rulers. During this time two princes from Darrang, Supradhvaj and Makardhvaj, fled from their homeland due to internal clash, by crossing the mighty Brahmaputra and they settled at Bahakajari. Later on, Supradhvaj married the daughter of Mangal Singh, the King of Baghara. Supradhvaj was then made the seventh king of the region, having an independent kingdom of his own.

During the days of Lachit Borphukan, another two princes from Darrang, Ram Singh and Bhim Singh crossed the Brahmaputra in search of plain lands. After Bhim Singh settled down, meanwhile, Ram Singh left for his home. Bhim Singh was not liked by the local people, hence, he left Brahmaputra and settled down near Mori Beel. This place came to known as Morigaon.[1]

Morigaon became a fully-fledged district on 29 September 1989, when it was split from Nagaon district.[2]


Morigaon district occupies an area of 1,704 square kilometres (658 sq mi),[3] comparatively equivalent to Samoa's Savai'i.[4] The district is bounded by the mighty Brahmaputra on the North, Karbi Anglong district on the South, Nagaon District on the East and Kamrup District on the West. The greater part of the district is an alluvial plain, criss-crossed with numerous rivers and water ways and dotted with many beels and marshes. The mighty Brahmaputra flows along with the northern boundary of the district.

Killing, Kolong and Kopili rivers flow through the southern part of the district. The Killing meets the Kopili at the Matiparbat where from Kopili moves westward. The Kolong joins Kopili at the Jagi Dui Khuti Mukh and from here they jointly fall into the Brahmaputra. The general appearance of the district is extremely picturesque. On a clear day in the winter the view to the north is bounded by the blue ranges of the outer Himalayas, behind which snowy peaks glisten brightly in the sun, while to the west and the south of the district lie range upon range of lower hills, whose sides are covered with luxuriant vegetation of the tropical forest.


In 2006, the Indian government named Morigaon one of the country's 250 most backward districts (out of a total of 640).[5] It is one of the eleven districts in Assam currently receiving funds from the Backward Regions Grant Fund Programme (BRGF).[5]



There are three Assam Legislative Assembly constituencies in this district: Jagiroad, Morigaon, and Laharighat.[6] Jagiroad is designated for Scheduled Castes. All three are in the Nowgong Lok Sabha constituency.[7]

The Census of India divides Morigaon district into the following five subdistricts, or circles: Bhuragaon, Laharighat, Marigaon, Mayong, and Mikirbheta.[8] Each of these circles contains a large number of villages; for example Marigaon circle consists of one city and 162 villages.[9] Among these, Ahaturi Natua Gaon in Marigaon circle is a large village, administered by a sarpanch, and has a population of 2951.[10]
