University College (UniCol), founded in 1969, is the largest residential hall at the University of Otago in Dunedin, New Zealand. It houses approximately 501 residents during the academic year. Originally consisting of two towers, North Tower and South Tower, it has since been expanded with the acquisition of a set of flats on Clyde street and then in 2004 with the Northern and Southern Annexes. It is the most central college on the campus, situated beside the university's original buildings.
