The University of Oxford is a university in Oxford, England. It is the oldest university in the English-speaking world. The Times Higher Education World University Rankings stated that "it is the best university in the world" in the 2000s.

The university is 38 colleges and six private halls. All of these colleges have their own buildings and their own staff. Oxford is quite different from most modern universities where all the students live on a campus. Oxford does not have a campus, although it does have some central places where students from different colleges can come together (for example, libraries).

The Bodleian Library (founded in 1602) is the main library of the University of Oxford, and one of the oldest libraries in Europe. It is the second largest library in the United Kingdom after the British Library.
