Saïd Business School (Oxford Saïd or SBS) is the business school of the University of Oxford.

Business and management classes started at Oxford in 1965 when the Centre of Management Studies, later relaunched as Templeton College, Oxford, was founded. In 1988, a committee chaired by Claus Moser, Baron Moser recommended that the University create a new School of Management Studies. By 1990, Clark L. Brundin became founding director of Oxford's school of management studies. In 1996, the school re-branded as Saïd Business School after a donation of £28 million from Wafic Saïd. New premises were built on Park End Street and opened in 2001. The Thatcher Business Education Centre was opened on the same site in 2012 after a further donation from Saïd. The School has another centre at Egrove Park, on the former site of Templeton College, and in 2019 acquired an old power station in Osney to convert into a Global Leadership Centre.

Saïd Business School is the University of Oxford's department for graduate students in business, management and finance. Undergraduates are also taught as part of the Economics and Management course together with the Economics Department.

As of September 2025, Professor Mette Morsing was appointed Interim Dean following the resignation of Professor Soumitra Dutta over allegations of harassment made by a female colleague.
