City Hall Plaza in Boston, Massachusetts, is a large, open, public space in the Government Center area of the city. The architectural firm Kallmann McKinnell & Knowles designed the plaza in 1962 to accompany Boston's new City Hall building. The multi-level, irregularly shaped plaza consists of red brick and concrete. The Government Center MBTA station is located beneath the plaza; its entrance is at the southwest corner of the plaza.

Government Center is an area in downtown Boston, centered on City Hall Plaza. Formerly the site of Scollay Square, it is now the location of Boston City Hall, courthouses, state and federal office buildings, and a major MBTA subway station, also called Government Center. Its development was controversial, as the project displaced thousands of residents and razed several hundred homes and businesses.
