Nuffield College is one of the constituent colleges of the University of Oxford in England. It is a graduate college specialising in the social sciences, particularly economics, politics and sociology. Nuffield is one of Oxford's newer colleges, having been founded in 1937, as well as one of the smallest, with only around 90 students and 60 academic fellows. It was also the first Oxford college to accept both men and women, having been coeducational since foundation, as well as being the first college exclusively for graduate students in either Oxford or Cambridge.

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.
