Cotton University is a public state university located in Guwahati, Assam, India. It was established under The Cotton University Act, 2017 of the Assam Legislative Assembly to merge the Cotton College State University (CCSU) and Cotton College. Cotton College was established in 1901 by Sir Henry Stedman Cotton, the Chief Commissioner of the erstwhile British province of Assam. It had been the oldest institute of higher education in Assam and the whole northeast India. It became the constituent college of Gauhati University in 1948, and then that of the Cotton College State University, when CCSU was established by an Act (Act XIX of 2011) of the Assam Government in 2011. The Cotton University Act, 2017 was made to resolve the problems between the college and the university.
