Gloucester College, Oxford, was a Benedictine institution of the University of Oxford in Oxford, England, from the late 13th century until the dissolution of the monasteries in the 16th century. It was never a typical college of the University; in that there was an internal division in the college, by staircase units, into parts where the monasteries sending monks had effective authority. The overall head was a Prior, later changed to a Prior Studentium, and finally a Principal.

Worcester College is one of the constituent colleges of the University of Oxford in England. The college was founded in 1714 by the benefaction of Sir Thomas Cookes, 2nd Baronet (1648–1701) of Norgrove, Worcestershire, whose coat of arms was adopted by the college. Its predecessor, Gloucester College, had been an institution of learning on the same site since the late 13th century until the Dissolution of the Monasteries in 1539. Founded as a men's college, Worcester has been coeducational since 1979. The provost is David Isaac, CBE who took office on 1 July 2021
