Forest Park is a Victorian garden district located in Springfield, Massachusetts, developed between 1880 and 1920. It is the city's most populous neighborhood, and surrounds the 735-acre Frederick Law Olmsted–designed Forest Park, for which the neighborhood is named. The Forest Park neighborhood has nature and recreation within walking distance. To the west, I-91 separates Forest Park from the Connecticut River. A 195-acre section of the neighborhood was listed on the National Register of Historic Places in 1982 as the Forest Park Heights Historic District.
