List of municipalities in Massachusetts

This map^{[clarification needed]} shows towns colored by the date they were incorporated in Massachusetts since the founding of Plimoth Plantation in 1620. Many of the towns and future cities shown covering the area of their original incorporation have since been divided into two, three or in some cases several 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.
