Hampstead is a town in Rockingham County, New Hampshire, United States.

The town was incorporated in 1749 by colonial governor Benning Wentworth, who renamed it after Hampstead, England,[3] the residence of William Pitt, a close friend.

The Hampstead Meetinghouse, constructed circa 1749–1768, was added to the National Register of Historic Places in 1980.

The highest point in Hampstead is greater than 460 feet (140 m) above sea level at the town's northwestern corner, near the eastern knob of Butman Hill.

Hampstead lies mostly within the Merrimack River watershed, though the area east of Butman Hill and north of Smith Mountain is part the Piscataqua River (Coastal) watershed.

Local public schools include: The Town of Hampstead pays tuition for town students to attend Pinkerton Academy in Derry, and therefore Pinkerton serves as Hampstead's public high school.
