Goffstown is a town in Hillsborough County, New Hampshire, United States. The population was 17,651 at the 2010 census. The compact center of town, where 3,196 people resided at the 2010 census, is defined by the U.S. Census Bureau as the Goffstown census-designated place and is located at the junction of New Hampshire routes 114 and 13. Goffstown also includes the villages of Grasmere and Pinardville. The town is home to Saint Anselm College (and its New Hampshire Institute of Politics) and is the former location of the New Hampshire State Prison for Women, prior to the prison's relocation to Concord in 2018. The former prison in Goffstown is now vacant.
Prior to the arrival of English colonists, the area had been inhabited for thousands of years by succeeding cultures of Native Americans; its waterways had numerous fish and the area had game.
The town was first granted as "Narragansett No. 4" in 1734 by New Hampshire and Massachusetts Colonial Governor Jonathan Belcher as a Massachusetts township (the area then being disputed between the two provinces). It was one of seven townships intended for soldiers (or their heirs) who had fought in the "Narragansett War" of 1675, also known as King Philip's War. In 1735, however, some grantees "found it so poor and barren as to be altogether incapable of making settlements," and were instead granted a tract in Greenwich, Massachusetts.
