Massachusetts is a state located in the Northeastern United States. Municipalities in the state are classified as either towns or cities, distinguished by their form of government under state law. Towns have an open town meeting or representative town meeting form of government; cities, on the other hand, use a mayor-council or council-manager form. Based on the form of government, as of 2023, there are 292 towns and 59 cities in Massachusetts. Over time, many towns have voted to become cities; 14 municipalities still refer to themselves as "towns" even though they have a city form of government. The Census Bureau classifies towns in Massachusetts as a type of "minor civil division" and cities as a type of "populated place". However, from the perspective of Massachusetts law, politics, and geography, cities and towns are the same type of municipal unit, differing primarily in their form of government and some state laws which set different rules for each type. There is no unincorporated land in Massachusetts. The land area of the state is completely divided up among the 351 municipalities.

Geography of towns at formation

Many municipalities have at some point been divided into two or more smaller municipalities. For example, Dorchester was incorporated in 1630 and originally included all of the current Dorchester, now the largest neighborhood of Boston, plus the Boston neighborhood of Mattapan, and all of present-day Quincy, Milton, Braintree, Randolph, Holbrook, Canton, Sharon, Stoughton, Avon and the northeast portion of Foxboro. Nearly all of Massachusetts territory had been incorporated by 1815, with the final three areas of Erving (1838), Gay Head (now Aquinnah) and Mashpee (both 1870) being incorporated from previously Native American land.

Some towns and cities were annexed to others; disincorporated; or ceded to another state in their entirety. This list does not include territory changes affecting only part of a municipality; see History of Massachusetts.
