The main buildings of Jesus College, one of the colleges of the University of Oxford, are located in the centre of the city of Oxford, England, between Turl Street, Ship Street, Cornmarket Street, and Market Street.
 Jesus College was founded in 1571 by Elizabeth I upon the petition of a Welsh clergyman, Hugh Price, who was treasurer of St David's Cathedral.
 Her foundation charter gave to the college the land and buildings of White Hall, a university hall that had experienced a decline in student numbers.
 Price added new buildings to those of White Hall, and construction work continued after his death in 1574.
 The first of the college's quadrangles, which includes the hall, chapel, and principal's lodgings was completed between 1621 and 1630.
 Construction of the second quadrangle began in the 1630s, but was interrupted by the English Civil War and was not completed until about 1712.
 Further buildings were erected in a third quadrangle during the 20th century, including science laboratories (now closed), a library for undergraduates, and additional accommodation for students and fellows.
 In addition to the main site, the college owns flats in east and north Oxford, and a sports ground.
