Kamrup district (/ˈkæmˌrəp/ or /ˈkæmˌruːp/), is an administrative district in the state of Assam in India formed by dividing the old Kamrup district into two in the year 2003; other being Kamrup Metropolitan district, named after the region it constitutes. This district, along with Nalbari, Barpeta, Kamrup Metropolitan, Bajali and Baksa districts has been created from the Undivided Kamrup district. Rangiya is the Sub-District of Kamrup. The present Kamrup district has its headquarters at Amingaon.

Kamrup Rural district was created by bifurcating Undivided Kamrup district in 2003.

The Government of Assam, during the Chief-ministership of Late Tarun Gogoi, had proposed to bifurcate it further and create a new district, named South Kamrup. In 2016, the process of creation of the district was started. However, later that year, the process of creation was stopped midway due to lack of infrastructure.

Kamrup district occupies an area of 4,345 square kilometres (1,678 sq mi). Kamrup district has some territorial disputes with neighbouring West Khasi Hills district, Meghalaya, including that over the village of Langpih.^{[citation needed]}

In the immediate neighborhood of the Brahmaputra, the land is low and exposed to annual inundation. In this marshy tract reeds and canes flourish luxuriantly, and the only cultivation is that of rice. At a comparatively short distance from the river banks the ground begins to rise in undulating knolls towards the mountains of Bhutan on the north, and towards the Khasi hills on the south. The hills south of the Brahmaputra in some parts reach the height of 800 feet (240 m). The Brahmaputra, which divides the district into two nearly equal portions, is navigable by river steamers throughout the year, and receives several tributaries navigable by large native boats in the rainy season. The chief of these are the Manas, Chaul Khoya and Barnadi on the north, and the Kulsi and Dibru on the south bank.

In 1989 Kamrup district became home to the Dipor Bil Wildlife Sanctuary, which has an area of 4.1 km² (1.6 mi²). There is also a plantation where seedlings of teak, sal, sissu, sum, and nahor are reared, and experiments are being made with the caoutchouc tree.

Kamrup is home to one of the few large colonies of greater adjutant storks still in existence. The villagers previously regarded the birds as pests, but outreach efforts including cultural and religious programming, especially aimed at local women, have rallied Kamrup residents to be proud of and protect the storks.

According to the 2011 census Kamrup district has a population of 1,517,542, roughly equal to the West African country of Gabon or the US state of Hawaii. This gives it a ranking of 327th in India (out of a total of 640). The district has a population density of 436 inhabitants per square kilometre (1,130/sq mi) . Its population growth rate over the decade 2001-2011 was 15.67%. Kamrup has a sex ratio of 946 females for every 1000 males, and a literacy rate of 72.81%. Scheduled Castes and Scheduled Tribes made up 7.11% and 12.00% of the population respectively.
