Kingston is a town in Rockingham County, New Hampshire, United States. The population at the 2010 census was 6,025.
Kingston was the fifth town to be established in New Hampshire. Originally, it was a part of Hampton, New Hampshire. After King Philip's War, the establishment of new settlements was made possible by peace treaties with the local Indian tribes and, in 1692, by geographical and jurisdictional agreements between the provinces of Massachusetts and New Hampshire. Consequently, certain residents of Hampton, New Hampshire petitioned for a grant of a separate township to be created from the western part of Hampton. And so, in 1694, King William of England granted a royal charter establishing the town of ''Kingstown'', so named in honor of the King. Use of the title rather than the King's name was common at the time. The original charter still exists to this day.
The Kingston historic district encompasses the town center of Kingston. Historic buildings and sites within the district include the Kingston town hall; the Josiah Bartlett House, home of the second signer of the U.S. Declaration of Independence; the First Universalist Church; the Sanborn Seminary; the Nichols Memorial Research Library; the Kingston Historical Museum (housed in the town's first fire house); The 1686 House restaurant; the Masonic building; the Cemetery at the Plains (where Josiah Bartlett is buried); the Church on the Plains, and the Grace Daley House and barn, home to the town's first church owned parsonage (1835).
