Jackson is a town in Carroll County, New Hampshire, United States. The population was 1,028 at the 2020 census, up from 816 at the 2010 census. Jackson is a resort area in the White Mountains. Parts of the White Mountain National Forest are in the west, north and east.
Once consisting of several large land grants by colonial Governor John Wentworth, the town was first named "New Madbury", after the seacoast town of Madbury. In 1772, a road was built through Pinkham Notch, and the area was first settled in 1778 by Benjamin Copp and his family. In 1800, the community was renamed in honor of President John Adams, who was then in office. The name "Adams" stuck until the town was incorporated in 1829, when Andrew Jackson, the hero of the Battle of New Orleans, was inaugurated president. Governor Benjamin Pierce, a staunch backer of President Jackson, was influential in changing the name to Jackson. Only one vote was cast against the switch. In 2021, town residents voted to rededicate the town name to honor geologist Charles Thomas Jackson (1805–1880) rather than Andrew Jackson.
In 1847, artists of the White Mountain School began arriving in Jackson to paint the scenic beauty of the White Mountains. Others would follow, and in 1858, Joshua B. Trickey opened the Jackson Falls House. The Portland & Ogdensburg Railroad began service to Glen station at nearby Bartlett in the early 1870s, and several hotels were built to accommodate a growing infusion of tourists. Thorn Mountain House, built by Trickey in 1869, would evolve during the 1880s into Wentworth Hall, still in business today. Designed as a grouping of cottages around a main service building, the hotel included such amenities as a casino, built in 1886, and a hydroelectric plant, built in the 1890s. By the 1920s, 40 trains a day delivered passengers to Jackson.
The increasing use of automobiles, however, reduced travel by train, as vacationers could venture beyond the limits of rail service. Consequently, some grand 19th century hotels lost patrons and closed, although the town itself would never lose popularity.
