The Harvard Square Subway Kiosk is a historic kiosk and landmark located in Harvard Square in Cambridge, Massachusetts. It was built in 1928 as the new main headhouse (entrance building) for the previously-opened Harvard Square subway station. After the station closed in 1981 for major renovations, the kiosk was moved slightly and renovated. The Out of Town News newsstand, which opened in 1955, occupied the kiosk from 1984 to 2019. As of 2019, the City of Cambridge (which owns the structure) plans to convert it for public use.
