University College (in full The Master and Fellows of the College of the Great Hall of the University of Oxford, colloquially referred to as "Univ"), is a constituent college of the University of Oxford in England. As of 2009 the college had an estimated financial endowment of £110m. As it was founded in 1249, it is the oldest Oxbridge college.

Some claim the college was founded by King Alfred in 872. However most agree its foundation was in 1249 by William of Durham. This later date still allows the claim that Univ is the oldest of the Oxford colleges. Until the 16th century it was only open to Fellows studying theology. As Univ grew in size and wealth, its medieval buildings were replaced with the current Main Quadrangle in the 17th Century. Although the foundation stone was placed on 17 April 1634 the disruption of the English Civil War meant it was not completed until sometime in 1676.Radcliffe Quad followed more rapidly by 1719, and the Library was built in 1861. Univ began to accept female undergraduate students in 1979.
