The Old Addenbrooke's Site is a site owned by the University of Cambridge in the south of central Cambridge, England. It is located on the block formed by Fitzwilliam Street to the north, Tennis Court Road to the east, Lensfield Road to the south, and Trumpington Street to the west. Addenbrooke's Hospital was founded in 1766 on Trumpington Street, but in 1976 it relocated to larger premises further out of the city to the southeast at the end of Hills Road, hence the name of this site now.
