This is a list of the colleges within the University of Cambridge. These colleges are the primary source of accommodation for undergraduates and graduates at the University and at the undergraduate level have responsibility for admitting students and organising their tuition. They also provide funding and/or accommodation for some of the senior research posts in the University. The colleges are self-governed charitable institutions on their own right, with their own endowments and possessions. Until the mid-19th century, both Cambridge and Oxford were rather a group of colleges with a small central university administration, than universities in the common sense.
