The Oxford University Student Union is the official students' union of the University of Oxford. It is better known in Oxford by its acronym, OUSU (/ˈaʊzuː/ OW-zoo). It exists to represent Oxford University students in the University's decision-making, to act as the voice for students in the national higher education policy debate, and to provide direct services to the student body. It is not to be confused with the Oxford Union debating society, which, although similarly named, is separate private club with no representative functions.
