Worcester College is one of the constituent colleges of the University of Oxford in England. The college was founded in 1714 by the benefaction of Sir Thomas Cookes, 2nd Baronet (1648–1701) of Norgrove, Worcestershire, whose coat of arms was adopted by the college. Its predecessor, Gloucester College, had been an institution of learning on the same site since the late 13th century until the Dissolution of the Monasteries in 1539. Founded as a men's college, Worcester has been coeducational since 1979. The provost is David Isaac, CBE who took office on 1 July 2021

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.
