St Anne's College is a constituent college of the University of Oxford in England. It was founded in 1879 and gained full college status in 1959. Originally a women's college, it has admitted men since 1979. It has some 450 undergraduate and 200 graduate students and retains an original aim of allowing women of any financial background to study at Oxford. It still has a student base with a higher than average proportion of female students. The college stands between Woodstock and Banbury roads, next to the University Parks. In April 2017, Helen King, a retired Metropolitan Police Assistant Commissioner, took over as Principal from Tim Gardam. Former members include Danny Alexander, Edwina Currie, Ruth Deech, Helen Fielding, William MacAskill, Amanda Pritchard, Simon Rattle, Tina Brown, Mr Hudson and Victor Ubogu.

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.
