Harris Manchester College (HMC) 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 University of Oxford has thirty-nine colleges, and four permanent private halls (PPHs) of religious foundation. Colleges and PPHs are autonomous self-governing corporations within the university. These colleges are not only houses of residence, but have substantial responsibility for teaching undergraduate students. Generally tutorials and classes are the responsibility of colleges, while lectures, examinations, laboratories, and the central library are run by the university. Students normally have most of their tutorials in their own college, but often have a couple of modules taught at other colleges or even at faculties and departments. Most colleges take both graduates and undergraduates, but several are for graduates only.
