Darrang (Assamese pronunciation: [dɔrɔŋ]) is an administrative district in the state of Assam in India.

According to scholar Late Dineshwar Sarma, the name comes from the Assamese word "Doar," meaning "door," which refers to the alluvial floodplains in eastern and northeastern India that have long served as passageways for traders and travelers from the Himalaya and also as critical entry point for merchants from regions such as China, Tibet, Bhutan, and Central Asia.

[2] By early 17th century, the Kingdom of Bhutan took control of the Darrang Duars as far as Gohain Kamal Ali road.

[3][4] The Bhutan control over these regions were through local authorities, who were appointed by Bhutanese provincial governors called Ponlops.

On 28 January 1894, there was a peasant's uprising against the increased land revenue by the British Raj in Patharighat, a village in Darrang district.

In the British response that followed, 140 peasants belonging to both Hindu and Muslim communities died from bullet wounds and another 150 were injured.

[9] Darrang is home to Orang National Park, which it shares with Sonitpur district.

[10] There are four Assam Legislative Assembly constituencies in this district: Kalaigaon, Sipajhar, Mangaldoi, and Dalgaon.
