Bongaigaon (Assamese: বঙাইগাঁও ) is the district headquarters of Bongaigaon District, Assam, India. The city is situated 180 kilometres (112 mi) north west of Guwahati.It is a very developing City in Lower Assam. It has two parts - Old Bongaigaon and New Bongaigaon. Bongaigaon is predominantly inhabited by the Koch Rajbongshi Community which is a part of "Bijni Kingdom" ruled by the Koch Rajbongshi Kings. Recently it was divided and a new district Chirang was formed. It has a major petrochemical industry, the Indian Oil Corporation Limited.

From the chequered historical background of this district, it can easily be surmised that the entire area was ruled by Kings/Zaminders/Feudal Lords hailing from the Koch-Rajbongshies belonging to Indo-Mongoloid ethnic group of peoples right from 15th century to the end of princely states in 1956 A.D. The kings of this area had their hoary past and can be traced back to the "Kiratees" of epic age (Mahabharata fame) that is pre-vedic age. These Kiratees of dimpast are also mentioned in Kalika Puran and Jogingi Tantra and also in histories written both by native and foreign schoolers.
