Harvard Square is a triangular plaza at the intersection of Massachusetts Avenue, Brattle Street, and John F. Kennedy Street, near the center of Cambridge, Massachusetts, United States. The term "Harvard Square" is also used to delineate the business district and Harvard University surrounding that intersection, which is the historic center of Cambridge. Adjacent to Harvard Yard, the historic heart of Harvard University, the Square (as it is sometimes called locally) functions as a commercial center for Harvard students, as well as residents of western Cambridge and the western and northern neighborhoods and inner suburbs of Boston. The Square is served by Harvard station, a major MBTA Red Line subway and bus transportation hub.
