List of municipalities in Massachusetts in the context of "Springfield, Massachusetts"

Boston is the capital and most populous city of the U.S. state of Massachusetts. It serves as the cultural and financial center of New England, a region of the Northeastern United States. Boston has an area of 48.4 sq mi (125 km) and a population of 675,647 as of the 2020 census, making it the third-most populous city in the Northeastern United States after New York City and Philadelphia. The larger Greater Boston metropolitan statistical area had a population of 4.9 million in 2023, making it the largest metropolitan area in New England and the eleventh-largest in the United States.

Boston was founded on Shawmut Peninsula in 1630 by English Puritan settlers, who named the city after the market town of Boston, Lincolnshire in England. During the American Revolution and Revolutionary War, Boston was home to several seminal events, including the Boston Massacre (1770), the Boston Tea Party (1773), Paul Revere's midnight ride (1775), the Battle of Bunker Hill (1775), and the Siege of Boston (1775–1776).

Cambridge (/ˈkeɪmbrɪdʒ/ KAYM-brij) is a city in Middlesex County, Massachusetts, United States. It is a suburb in the Greater Boston metropolitan area, located directly across the Charles River from Boston. The city's population as of the 2020 U.S. census was 118,403, making it the most populous city in the county, the fourth-largest in Massachusetts behind Boston, Worcester, and Springfield, and ninth-most populous in New England. The city was named in honor of the University of Cambridge in Cambridge, England, which was an important center of the Puritan theology that was embraced by the town's founders.

Founded in December 1630 during the colonial era, Cambridge was one among the first cities established in the Thirteen Colonies, and it went on to play a historic role during the American Revolution. In May 1775, approximately 16,000 American patriots assembled in Cambridge Common to begin organizing a military retaliation against British troops following the Battles of Lexington and Concord. On July 2, 1775, two weeks after the Second Continental Congress in Philadelphia formally established the Continental Army and appointed George Washington commander of it, Washington arrived at Cambridge Common to take command of the Patriot soldiers camped there. Many of these soldiers played a role in supporting Washington's successful siege of Boston, which trapped garrisoned British troops from moving by land, forcing the British to ultimately abandon Boston. Cambridge Common is thus celebrated as the birthplace of the Continental Army.

Lynn is the eighth-largest municipality in Massachusetts, United States, and the largest city in Essex County. Situated on the Atlantic Ocean, 3.7 miles (6.0 km) north of the Boston city line at Suffolk Downs, Lynn is part of Greater Boston's urban inner core and is a major economic and cultural center of the North Shore.

Settled by Europeans in 1629, Lynn is the 5th oldest colonial settlement in the Commonwealth. An early industrial center, Lynn was long colloquially referred to as the "City of Sin", owing to its historical reputation for crime and vice. Today, however, the city is known for its immigrant population, historic architecture, downtown cultural district, loft-style apartments, and public parks and open spaces, which include the oceanfront Lynn Shore Reservation; the 2,200-acre, Frederick Law Olmsted-designed Lynn Woods Reservation; and the High Rock Reservation and Park designed by Olmsted's sons. Lynn also is home to Lynn Heritage State Park, the southernmost portion of the Essex Coastal Scenic Byway, and the seaside, National Register-listed Diamond Historic District. The population was 101,253 at the 2020 United States census.

Worcester (/ˈwʊstər/ WUUST-ər, locally [ˈwɪstə] ) is a city in the U.S. state of Massachusetts. The principal city of Central Massachusetts, Worcester is both the second-most populous city in the state, and the 113th most populous city in the United States. Named after Worcester, England, the city had 206,518 people at the 2020 census, also making it the second-most populous city in New England, after Boston. Because it is near the geographic center of Massachusetts, Worcester is known as the "Heart of the Commonwealth"; a heart is the official symbol of the city. Worcester is the historical seat of Worcester County.

Founded in 1722 and incorporated in 1848, Worcester developed as an industrial city in the 19th century due to the Blackstone Canal and railways, which facilitated the import of raw materials and the export of such finished goods as machines, textiles, and wire. The city's population grew, driven by European immigration. After World War II, manufacturing in Worcester waned, and the city declined economically and in terms of population. This trend was reversed in the 1990s, when higher education, medicine, biotechnology, and new immigrants started making their mark. The population has grown by 28% since 1980, reaching its all-time high in the 2020 census, in an example of urban renewal. Since the 1970s, and especially since the construction of Route 146 and interstates 90, 495, 190, 290, and 395, both Worcester and its surrounding towns have become more integrated with Boston's suburbs. The Worcester region now marks the western periphery of the Boston–Worcester–Providence (MA–RI–NH) U.S. census Combined Statistical Area (CSA), or Greater Boston.

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.
