The Southwest Corridor Park is a state park and recreation area in Jamaica Plain, Massachusetts. It is a linear urban park that is a part of the Metropolitan Park System of Greater Boston that is managed by the Massachusetts Department of Conservation and Recreation.

The Southwest Corridor Park was originally a residential area. It was initially planned to be transformed into a highway, known as the Southwest Expressway. Houses were already razed for the project but local residents protested against it in the 1960s, with the bulldozers getting blocked by actual locals? bodies. The project was canceled in 1969 and became a park in 1978, after the residents? efforts to grow community gardens in the area.

Visitors of the Southwest Corridor Park today can enjoy biking and walking along its scenic paths, as well as playing in its basketball and tennis courts. There are also some spray pools and tot lots at the site.
