Hampton Falls (formerly the Third Parish and Hampton falls) is a New England town in Rockingham County, New Hampshire, United States. The population was 2,236 at the 2010 census.

The land of Hampton Falls was first settled by Europeans in 1638, the same time as Hampton, which it was then part of. The settlement of Hampton joined Norfolk County, Massachusetts Colony, in 1643, along with Exeter, Dover, Portsmouth, and Salisbury and Haverhill of Massachusetts. The county existed until 1679, when the modern-day New Hampshire towns separated from Massachusetts Bay Colony.

Records indicate a building that became a church may have existed near where the Weare Monument now is in 1665, but when it was first built is unknown. It was not until 1709 that the town was officially established as the Third Parish of Hampton. The Third Parish originally consisted of all land south of the Taylor River and north of the New Hampshire/Massachusetts border, or the modern-day towns of Seabrook, Kensington, and Hampton Falls. A meeting house was built shortly after and Thomas Crosby became the town's minister for the church. Forty-nine members of the Hampton Church were dismissed late in 1711, only to become members of the new church in the Third Parish. Parish officers and a representative were chosen in 1718. The first town meeting was held and town records began that year also. The 7,400-acre (30 km²) town received its grant as an independent town with the name "Hampton falls" in 1726, but was still referred to as a parish until the Revolutionary War. Those who did use its actual name in writing spelled it with a lowercase f until around the same time.
