South Boston is a densely populated neighborhood of Boston, Massachusetts, located south and east of the Fort Point Channel and abutting Dorchester Bay. South Boston, colloquially known as Southie, 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. South Boston contains Dorchester Heights, where George Washington forced British troops to evacuate during the American Revolutionary War. South Boston has undergone gentrification, and consequently, its real estate market has seen property values join the highest in the city. South Boston has also left its mark on history with Boston busing desegregation. South Boston is also home to the St. Patrick's Day Parade, a celebration of the Irish-American culture and the Evacuation Day observance. The headquarters of Reebok is in South Boston.

Dorchester Heights is the central area of South Boston. It is the highest area in the neighborhood and commands a view of both Boston Harbor and downtown.

The Fortification of Dorchester Heights was a decisive action early in the American Revolutionary War that precipitated the end of the siege of Boston and the withdrawal of British troops from that city. On March 4, 1776, troops from the Continental Army under George Washington's command occupied Dorchester Heights, a series of low hills with a commanding view of Boston and its harbor, and mounted powerful cannons there threatening the city and the Navy ships in the harbor. General William Howe, commander of the British forces occupying Boston, planned an attack to dislodge them. However, after a snowstorm prevented its execution, Howe withdrew instead. British forces, accompanied by Loyalists who had fled to the city during the siege, evacuated the city on March 17 and sailed to Halifax, Nova Scotia.

A discontiguous segment of Columbia Road running southwest from Kosciuszko Circle into Dorchester is not part of the parkway system. the part of Old Colony Avenue from its southern end near Kosciuszko Circle, northward to Pacuska Circle. This section of road forms the western border of Joe Moakley Park. Old Colony Avenue north of Pacuska Circle is not part of the parkway system.These roadways follow the southern shoreline of South Boston west from Castle Island, and surround what is now known as Joe Moakley Park.

The South Boston CSO Storage Tunnel, also known as the North Dorchester Bay CSO Storage Tunnel, is a large underground facility designed to reduce untreated sewage discharges into Boston Harbor from the Massachusetts Water Resources Authority combined sewer and stormwater system. It was opened on July 23, 2011, and is part of the federally mandated Boston Harbor Cleanup project. CSO stands for Combined Sewer Overflow. The main part of the facility is a tunnel 17 feet (5.2 m) in diameter, running 2.5 miles (4.0 km) along the harbor front. The tunnel starts at an Odor Control Building (42.3225°N 71.0490°W / 42.3225; -71.0490 (Odor Control Building)), continues along the harbor front, with a midpoint near 42.3294°N 71.0373°W / 42.3294; -71.0373, and ends with a pump station at 42.3385°N 71.0216°W / 42.3385; -71.0216 (Pumping station).Combined sewers are problematic because during heavy storms, they are forced by a high volume of rainwater from storm drains to carry untreated sanitary sewer output into Boston harbor, including dangerous amounts of human waste. In addition to the tunnel project, the MWRA is undertaking costly sewer separation in parts of South Boston near the Reserved Channel, and reconfiguring various drains and outflows. The tunnel provides a buffer to allow some combined sewers to remain in service. It has sufficient buffer capacity to hold combined sewage and rain water during most storms, helping to eliminate the Combined Sewer Outflow events that polluted nearby beaches on average 20 times per year. After the storm is over, the tunnel is "dewatered" back into the network at a rate the Deer Island Waste Water Treatment Plant can handle.
