About Groton, MA

Groton is a town in northwestern Middlesex County, Massachusetts, United States, within the Greater Boston metropolitan area. The population was 11,315 at the 2020 census. It contains the census-designated place of the same name. An affluent bedroom community roughly 45 miles from Boston, Groton has a large population of professional workers, many of whom work in Boston's tech industry. It is loosely connected to Boston by highways (Route 2) and commuter rail (the MBTA Fitchburg Line). The town has a long history dating back to the colonial era. It was a battlefield in King Philip's War and Queen Anne's War, and several Grotonians played notable roles in the American Revolution (including William Prescott, the American commander at the Battle of Bunker Hill) and Shays' Rebellion. Groton is home to two college-preparatory boarding schools: Lawrence Academy at Groton, founded in 1793; and Groton School, founded in 1884. Notable Groton residents include former U.S. Secretary of State John Kerry, sports writers Peter Gammons and Dan Shaughnessy, and NBC political correspondent Steve Kornacki.
