Wilmington is a town in Middlesex County, Massachusetts, United States.
Wilmington was first settled in 1665 and was officially incorporated in 1730, from parts of Woburn, Reading, and Billerica. The first settler is believed to have been Will Butter, Richard Harnden or Abraham Jaquith. Butter was brought to Woburn as an indentured captive. Once he attained his freedom, he fled to the opposite side of a large swamp, in what is now Wilmington. Harnden settled in Reading, in an area that is now part of Wilmington. Jaquith settled in an area of Billerica that became part of Wilmington in 1740.
Minutemen from Wilmington responded to the alarm on April 19, 1775 and fought at Merriam's Corner in Concord.
The Middlesex Canal passed through Wilmington. Chartered in 1792, opened in 1803, it provided freight and passenger transport between the Merrimack River and Boston.
