Tyngsborough is a town in northern Middlesex County, Massachusetts, United States. Tyngsborough is 28 miles (45 km) from Boston along the Route 3 corridor, and located on theNew Hampshire state line. At the 2010 census, the town population was 11,292.
Tyngsborough was settled in 1661, as part of the massiveDunstable Township. The town of Dunstable, incorporated in 1673, was named after the hometown of pioneer Edward Tyng. However, a relative of his, and the source of the town of Tyngsborough's name, was Colonel Jonathan Tyng, whose home, the Tyng Mansion House, was one of the oldest north of Boston. He settled near the Merrimack in what is now Tyngsborough in 1675. The house stood until the 1970s, when it was destroyed by arson. Early on Tyngsborough residents fought a series of small and bloody skirmishes with local Native American tribes. Evidence of this can be found in several old colonial homes in town that still have emergency passages that were used during these attacks. In 1789, Tyngsborough's parish split from the rest of Dunstable, making Tyngsborough a recognized district. On February 23, 1809, Tyngsborough became a town.
