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

[2] First settled in 1763, Northwood was incorporated on February 6, 1773, by colonial governor John Wentworth, when a large tract of land called "North Woods" was separated from Nottingham.

At one time, there were some twelve sawmills in the town, five of which were replaced by shoe factories during the latter half of the 19th century.

More recently, the town has been a popular vacation spot, being home to nine lakes and many antique shops.

Four Northwood districts along Route 4 are considered historic sections of town.

The highest point in Northwood is Saddleback Mountain, at 1,150 feet (350 m) above sea level near the town's southern border.

18.0% of all households were made up of individuals, and 5.1% had someone living alone who was 65 years of age or older.
