The Open University (OU) is a public research university and the largest university in the United Kingdom by number of students. The majority of the OU's undergraduate students are based in the United Kingdom and principally study off-campus; many of its courses (both undergraduate and postgraduate) can also be studied anywhere in the world. There are also a number of full-time postgraduate research students based on the 45 ha (110-acre) university campus at Walton Hall in Milton Keynes, Buckinghamshire, where they use the staff facilities for research, as well as more than 1,000 members of academic and research staff and over 2,500 administrative, operational and support staff.

The OU was established in 1969 and was initially based at Alexandra Palace, north London, using the television studios and editing facilities which had been vacated by the BBC. The first students enrolled in January 1971. The university administration is now based at Walton Hall, but has administration centres in other parts of the United Kingdom. It also has a presence in other European countries. The university awards undergraduate and postgraduate degrees, as well as non-degree qualifications such as diplomas and certificates or continuing education units. It also offers unique Open Degrees, in which students may study any combination of modules across all subjects.

With around 200,000 students including around 34% of new undergraduates aged under 25 and more than 8,599 overseas students, it is the largest academic institution in the United Kingdom (and one of the largest in Europe) by student number, and qualifies as one of the world's largest universities. Since it was founded, more than 2.3 million students have studied with the Open University. The Open University is one of only two United Kingdom higher education institutions to gain accreditation in the United States by the Middle States Commission on Higher Education. It also produces more CEOs than any other United Kingdom university. Former United Kingdom Prime Minister Gordon Brown, astrophysicist Jocelyn Bell Burnell, broadcaster Anna Ford and actress Glenda Jackson are among those who have tutored for the OU.
