Campton is a town in Grafton County, New Hampshire, United States.

Both Campton and adjacent Rumney were granted by Governor Benning Wentworth in 1761 to Jabez Spencer of East Haddam, Connecticut, then settled about 1765.

But Captain Spencer died before terms of the charter, which required settlement by 50 families, each farming 5 acres (20,000 m2) for every 50 received, were fulfilled.

[4] Although the surface is mountainous and ledgy, farmers found good soil for cultivation in the intervales along the rivers.

By 1859, when the population was 1,439, industries included one sawmill, one gristmill, one tannery and a carriage shop.

[1] The highest point in Campton is Mount Weetamoo, at 2,548 feet (777 m) above sea level.
