Mansfield is a town in Tolland County, Connecticut, United States. The population was 25,892 at the 2020 census. Pequot and Mohegan people lived in this region for centuries before the arrival of English settler-immigrants in the late 17th century. Mansfield was incorporated in October 1702 from the Town of Windham, in Hartford County. The community was named after Major Moses Mansfield, a part owner of the town site.
