Karimganj District (Bengali: করিমগঞ্জ জিলা) is an administrative district in the state of Assam in India. The district headquarters are located at Karimganj.

The early history of present district of Karimganj, Assam, is hazy and obscure. With available source materials and evidences, it is difficult to construct a chronologically comprehensive account of early history of the region. Only a broad outline, with major gaps, can be attempted. From the Nidhanpur copper inscriptions issued by King Bhaskarbarman, it is learned that the region has been within the Kamrupa Kingdom for about a hundred years since A.D. sixth century. The Aryanisation of the region under the leadership of the pioneer immigrant Brahmins with plough-based agriculture as economic basis had its beginning during this period. From the Kalapur copper plates issued by Samata Marundanatha, it is learned that in the 7th Century A.D., this region, along with foothills of North Cachar Hills had passed on to the Samatata Kingdom of the Eastern Bengal. Of course, there is no direct evidence to prove it. In the 10th Century A.D., King Srichandra of the renowned Chandra Dynasty of Eastern Bengal incorporated the entire region within his Vanga Kingdom. During this period, the Chandrapura Matha or monastery, situated at Panchakhanda (8 miles From Karimganj town, now in Bangladesh), became a very reputed centre of learning. According to the renowned historian D.C. Sarkar, the Chandrapura Matha was the greatest centre of Hindu-learning in the entire Eastern India of the early period. From two Bhatera inscriptions of Govindakeshava Deva and Ishana Deva, it is learnt that there was an independent Srihatta Rajya in the 12th Century within which the entire Karimganj District along with a major portion of the Cachar plains were incorporated.

Karimganj Town (Bengali: করিমগঞ্জ) is a town in the Karimganj District of the Indian state of Assam. It is the administrative headquarter and main town of the district.

Karimganj town is located on the northern fringe of the district adjoining Bangladesh [1], flanked on two sides by the Kushiyara River and Longai river, Karimganj town is located just on the Bangladesh border with the river Kushiara flowing in between. One prominent feature of the place is a long and winding canal called Noti Khal meandering across the town. Earlier, it used to be a connecting river way between Kushiara and Longai facilitating river communication and also balancing of water-levels between the two rivers. Now, however, this canal has been blocked at several places through embankments and land-fills to pave way for road transport and construction works.

The distance of Karimganj town from Guwahati - the state capital of Assam - is approximately 330 km by road and about 350 km by rail. Distance of other important places are : Silchar - 55 km, Shillong - 220 km, Agartala - 250 km.
