Hertford College, previously known as Magdalen Hall, is a constituent college of the University of Oxford in England. It is located on Catte Street in the centre of Oxford, directly opposite the main gate to the Bodleian Library. The college is known for its iconic bridge, the Bridge of Sighs. There are around 600 students at the college at any one time, comprising undergraduates, graduates and visiting students from overseas.

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.
