Merrimac is a small town in Essex County, Massachusetts, United States, located on the southeastern border of New Hampshire, approximately 34 miles (55 km) northeast of Boston and 10 miles (16 km) west of the Atlantic Ocean.

They were held in bondage by town residents Isaac Merrill, Benjamin Morse, and Wells Chase.

[2] At least one former enslaved African, "Forte," who was sold by an unknown West Newbury slaver to Christopher Sargent, became locally famous for his fiddling after the abolition of slavery in Massachusetts.

In 1876, Merrimac, including Merrimacport, separated from Amesbury and officially incorporated itself as a town.

It is believed that the town, as well as the river that runs along its southern border, are both named for the American Indian tribe that occupied the region.

At the beginning of the twentieth century, as with the rest of the New England, it went through a period of deindustrialization as the region's industry relocated to the Midwest.

The communities of the Merrimack Valley, including Merrimac, were particularly affected by this long period of economic decline and have never fully recovered.

It went through numerous growth spurts throughout the 1990s and the beginning of the twenty-first century as it was absorbed into the Lawrence metropolitan area.

Located in the Merrimack River Valley and on the coastal plain of Massachusetts, Merrimac's land consists mainly of small, forested hills (before the twentieth century, it was mostly pasture).

The current chair of the board is Chris Manni, Ben Beaulieu is the clerk, and the other member is Irina Gorzynski.

[13] Per the constitution of the Commonwealth of Massachusetts, any resident of Merrimac may introduce legislation with the support of 10 registered voters.
