The Fields Corner Municipal Building is a historic municipal building at 1 Arcadia Street and 195 Adams Street in the Dorchester neighborhood of Boston, Massachusetts.

Built in 1875, it is a prominent local example of Victorian Gothic architecture, probably designed by the city's first official architect, George A. Clough.

The building originally housed a police station and library; it has been adaptively reused for professional and commercial purposes.

Its setting at the northwest corner of Adams and Arcadia Streets is just north of the angled intersection of Adams Street with Dorchester Avenue, which is the area's principal junction.

The building is 2-1/2 stories tall and built out of red brick with limestone trim.
