Located in Upper Assam on the south bank of the Brahmaputra river, it is one of the most economically important districts of the state owing to its tea, oil, natural gas and timber-based industries.

Geography
The district lies in the eastern part of the Brahmaputra valley. It is bounded by the Brahmaputra to the north, beyond which lies Dhemaji district, while Tinsukia district lies to the east, Sivasagar district to the west, and the hill districts of Arunachal Pradesh and Nagaland lie to its south and south-east. The terrain is largely alluvial plain, intersected by tributaries of the Brahmaputra such as the Buridihing and Dibru rivers. The district is prone to seasonal flooding and bank erosion along the Brahmaputra.
History
The area that now forms Dibrugarh district was historically part of the Ahom kingdom, which ruled much of Assam from the 13th to the early 19th century. Following the Treaty of Yandabo in 1826, the region passed under British control. The British developed Dibrugarh as an administrative and commercial centre in Upper Assam, particularly after the discovery of tea and the establishment of commercial tea gardens from the 1830s onwards. The town of Digboi, in the wider region, became the site of one of Asia's earliest oil refineries.
Dibrugarh was constituted as a separate district when it was carved out of the erstwhile Lakhimpur district. Tinsukia district was later separated from Dibrugarh, giving the district its present boundaries.
Administration
The district is administered by a Deputy Commissioner. For administrative purposes it is divided into subdivisions and revenue circles, and further into development blocks and gram panchayats. Major urban centres in the district include Dibrugarh, Naharkatia, Chabua, Tingkhong, Moran and Tengakhat.
Economy
The district's economy rests on three principal pillars:
- Tea: Dibrugarh is often referred to as the "Tea City of India" because of the large number of tea estates and processing facilities in and around it.
- Petroleum and natural gas: The Oil India Limited operates extensively in the area, and several oilfields, including those around Naharkatia and Moran, lie within or near the district.
- Agriculture and allied activities: Rice is the principal food crop, supplemented by mustard, pulses, sugarcane and horticultural produce.
Transport
Dibrugarh is well connected by road, rail and air. National Highway 37 passes through the district, linking it with the rest of Assam. The Dibrugarh railway station is a terminus for several long-distance trains, including services to Delhi and Kanyakumari. Dibrugarh Airport at Mohanbari provides air connectivity to major Indian cities. Inland water transport on the Brahmaputra continues to play a role in regional movement.
Education and institutions
Dibrugarh district hosts several institutions of regional and national importance, including:
- Dibrugarh University, established in 1965, the principal university of Upper Assam.
- Assam Medical College and Hospital, one of the oldest medical colleges in north-east India.
- Numerous government and private colleges affiliated to Dibrugarh University.
Demographics and culture
The population of the district is ethnically and linguistically diverse, with Assamese-speaking communities forming the majority. Significant communities include the Ahoms, Morans, Mataks, Sonowal Kacharis, Mishings and tea-tribe communities descended from labourers brought to Assam during the colonial period. Bihu, celebrated thrice a year, is the principal festival, alongside community-specific observances. The district is closely associated with Assamese literary, musical and theatrical traditions.
Significance
Dibrugarh district occupies a strategic position in Upper Assam, both economically and geopolitically. Its tea and petroleum industries contribute substantially to Assam's revenue, while its educational and medical institutions serve a wide catchment area extending into Arunachal
