The South Shore of Massachusetts is a geographic region stretching south and east from Boston toward Cape Cod along the shores of Massachusetts Bay and Cape Cod Bay. It is subject to varying descriptions including municipalities in eastern Norfolk and Plymouth counties. The South Shore is an affluent area. The median income of the region as of 2020 is $104,691. The median home value of the region as of 2020 is $574,831. Depending on its geographical definition, the South Shore is composed of a mix of suburban towns, mid-sized industrial cities and rural towns. Massachusetts' heaviest concentration of Irish-American residents and descendants from ancestors from Ireland is on the South Shore, and 6 of the United States' 10 most Irish towns are located on the South Shore, which is sometimes referred to locally as the Irish Riviera.

This definition eliminates Braintree, Quincy and Weymouth, which border Boston Harbor, but adds the towns of Hanover, Norwell and Pembroke. With respect to regional planning and cooperation among municipal governments, some of these coastal communities are either members of the Boston-centered Inner Core Committee of the Metropolitan Area Planning Council (MAPC) or not part of the metropolitan area at all, while the South Shore Coalition of the MAPC comprises representatives from 13 coastal and inland communities and includes the following cities and towns: The South Shore Chamber of Commerce includes all of the above towns, as well as several more farther inland in Norfolk and Plymouth counties, in its definition of the region: Informal definitions of South Shore—defined by the service areas of other nonprofits or businesses with "South Shore" in their names, by real estate agents, or by individuals, for example—always include at least some of the shoreline communities but can stretch considerably to the west.
