Salisbury is a town in Merrimack County, New Hampshire, United States. The population was 1,422 at the 2020 census.

While still part of Massachusetts, the town was granted as "Baker's Town" after Captain Thomas Baker in 1736. After the border between Massachusetts and New Hampshire was fixed, the town was on the New Hampshire side of the border. It was re-granted by the Masonian proprietors in 1749 with the name "Stevenstown", after Colonel Ebenezer Stevens of Kingston, New Hampshire, and settled as early as 1750. Additionally known as "Gerrishtown" and "New Salisbury", the name "Salisbury" was taken when the town incorporated in 1768.

According to the United States Census Bureau, the town has a total area of 39.8 square miles (103.1 km), of which 39.6 square miles (102.5 km) are land and 0.2 square miles (0.6 km) are water, comprising 0.56% of the town. The highest point in Salisbury is along its western boundary, where the eastern slopes of Mount Kearsarge climb to 1,910 feet (580 m) above sea level.

The Blackwater River, a southward-flowing tributary of the Contoocook River and part of the Merrimack River watershed, runs through the western side of the town. A popular fishing and recreation spot is The Bay, a natural lake-like section of the river. The east side of the town is drained by streams that run directly to the Merrimack River.
