Gloucester City Hall is located at 9 Dale Avenue in Gloucester, Massachusetts. It was built in 1870 and dedicated the following year, and has served as the main location for the city's offices since then. Built to a design by Bryant and Rogers, it is a two-story Second Empire brick building. Each of the rectangular building's four corners is topped by its own pyramidal roof structure, above which is a small rectangular cupola with its own roof. Centered on the front elevation is a clock tower that is brick in its lower levels, and decorated wood above, ending in a copper dome.
The building was listed on the National Register of Historic Places in 1973, and included in the Central Gloucester Historic District in 1982.
