The "Old Chelmsford" Garrison House (also known as the Old Chelmsford Garrison House Complex) is a historic house in Chelmsford, Massachusetts. It is the oldest house in Chelmsford, and has been preserved by the Garrison House Society as a museum. It was listed on the National Register of Historic Places in 1973. The exact date the building was erected is not known; it is claimed by the Society to have been built before 1691, when it is claimed to be one of the houses listed as a garrison house in Chelmsford, but a 1702 deed transferring land on which it stands does not mention it. Thomas Adams deeded the land to his son, Peletiah Adams, in 1683, and Peletiah deeded the land to his two sons in 1702, who probably built the house. Stylistic analysis of its construction also supports a post-1700 construction date. The same stylistic analysis casts doubt on the belief that the house actually served as a fortified garrison.Before the title passed to the Garrison House Society in 1952, only three families had previously owned it. Very few modifications had been made to it in all that time, making it a relatively accurate historic showpiece. The house now shares its lot with a barn, summer kitchen, a working blacksmith shop, an herb garden, a craft house and the "Hill Jock House," which was saved from destruction and moved in 2004 to the lot shared by the Old Chelmsford Garrison House.

Chelmsford () is a town in Massachusetts, United States. Established in 1655, it is located 24 miles (39 km) northwest of Boston. The Chelmsford militia played a role in the American Revolution at the Battle of Lexington and Concord and the Battle of Bunker Hill. Chelmsford was incorporated in May 1655 by an act of the Massachusetts General Court. When Chelmsford was incorporated, its local economy was fueled by lumber mills, limestone quarries and kilns. The farming community of East Chelmsford was incorporated as Lowell in the 1820s; over the next decades it would go on to become one of the first large-scale factory towns in the United States because of its early role in the country's Industrial Revolution. Chelmsford experienced a drastic increase in population between 1950 and 1970, coinciding with the connection of U.S. Route 3 in Lowell to Massachusetts Route 128 in the 1950s and the extension of U.S. Route 3 from Chelmsford to New Hampshire in the 1960s. Chelmsford has a representative town meeting form of government. The current town manager is Paul Cohen. The town has one public high school—Chelmsford High School, which is ranked among the top 500 schools in the nation—as well as two middle schools, and four elementary schools.
