Harris Manchester College is one of the constituent colleges of the University of Oxford in the United Kingdom. It was founded in Warrington in 1757 as a college for Unitarian students and moved to Oxford in 1893. It became a full college of the university in 1996, taking its current name to commemorate its predecessor the Manchester Academy and a benefaction by Lord Harris of Peckham.
The college is one of very few mixed-sex higher education colleges in the UK whose postgraduate and undergraduate places are exclusively for students aged 21 years or over.
