The United College of St Salvator and St Leonard (commonly referred to as United College) is one of the two statutory colleges of the University of St Andrews in St Andrews, Scotland. It was founded in 1747 by the merger of St Salvators College and St Leonard's College when the University was in decline.
The College encompasses the Faculties of Arts, Medicine and Science and is headed by the Master of the United College. The current Master of the United College is Professor Neville Richardson.
The college no longer functions as an administrative body and its use is purely formal. The other statutory college of the University is St Mary's College which encompasses the University's Faculty of Divinity. A third college, St Leonard's College was re-established in 1972 as a non-statutory college, which encompasses postgraduate and postdoctoral students.
