Fort Point Channel is a maritime channel separating South Boston from downtown Boston, Massachusetts, feeding into Boston Harbor. The south part of it has been gradually filled in for use by the South Bay rail yard and several highways. At its south end, the channel once widened into South Bay, from which the Roxbury Canal continued southwest where the Massachusetts Avenue Connector is now. The Boston Tea Party occurred at its northern end. The channel is surrounded by the Fort Point neighborhood, which is also named after the same colonial-era fort.

South Boston is a densely populated neighborhood of Boston, Massachusetts, United States, located south and east of the Fort Point Channel and abutting Dorchester Bay. It has undergone several demographic transformations since being annexed to the city of Boston in 1804. The neighborhood, once primarily farmland, is popularly known by its twentieth century identity as a working class Irish Catholic community. Throughout the twenty-first century, the neighborhood has become increasingly popular with millennial professionals.
