Allenstown is a town in Merrimack County, New Hampshire, United States. The population was 4,707 at the 2020 census, up from 4,322 at the 2010 census. Allenstown includes a portion of the village of Suncook. Just over one-half of the town's area is covered by Bear Brook State Park. == History == Allenstown takes its name from 17th-century provincial governor Samuel Allen. It was granted in 1721 but not incorporated until July 2, 1831. A part of neighboring Bow was annexed to Allenstown in 1815, and a portion of Hooksett was annexed in 1853. Most of the town's earliest settlement occurred in the eastern part of town along Deerfield Road, around the area now mostly occupied by Bear Brook State Park, and where the Old Allenstown Meeting House is located. Following the Civil War, the town's population shifted from the east to the west part of town, centered around the confluence of the Merrimack and Suncook rivers, in the area now known as Suncook. Railroads were instrumental to the development of Allenstown.
