Hampton Falls is a town in Rockingham County, New Hampshire, United States. The population was 2,403 at the 2020 census.
 Archaeological excavations have confirmed that what is now Hampton Falls has been occupied by humans for roughly 10,000 years.  The first settlers were indigenous peoples of the Northeastern Woodlands.
 The land of Hampton Falls was first settled by Europeans in 1638, the same time as Hampton, of which it was then a part. The settlement of Hampton joined Norfolk County, Massachusetts Colony, in 1643, along with Exeter, Dover, Portsmouth, Salisbury and Haverhill. The county existed until 1679, when the modern-day New Hampshire towns separated from the 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,[why?] 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.
 An attempt was made in 1732 to separate the western portion of Hampton Falls and make it a parish of Kingston. The proposal failed in a way, yet succeeded in another; the land was separated, but it did not become part of Kingston—in 1737 it became a town of its own, Kensington.
 A disease known as the "Throat Distemper" (now thought to have been a malignant form of diphtheria) infected the town with its symptoms in 1735 and 1736. 214 people of Hampton Falls perished, 96 of them being under the age of ten. Only two homes in town were throat distemper free. It passed through the town again in 1754, with far fewer casualties, but still many.
 Seventy-two people wanted Hampton Falls (which then included Seabrook and Kensington) to become a part of Massachusetts in 1739, including Meshech Weare, but the proposal failed in the end. In 1765, the Presbyterians of the town wanted to form a new parish in the southern portion of the town, where a church of their religion existed. A town meeting was held on December 30 when the rest of the villagers learned of the Presbyterians' plans, and it was decided that the town would be separated into two. The new parish was formed in 1768, and became incorporated under the name Seabrook shortly after. Hampton Falls was considered one of the leading manufacturing towns in the entire state of New Hampshire around the time of 1770.
 A plan to unite Seabrook and portions of Hampton Falls was proposed in 1782. The town would have been called "New Hampton Falls", but Hampton Falls was successful in making the proposal fail. In 1835, the town of Hampton Falls had a new meeting-house erected. Where in town it existed is unknown.
 On the night between October 29 and October 30 in 1827, an earthquake struck the small town. A flash of light from a fault in the southern region of the town occurred, with violent trembling shortly following. It caused at least three chimneys to collapse partially or completely, with several others cracked. A more severe earthquake had struck Hampton Falls on November 18, 1755.
 On May 21, 2006, an F2 tornado formed in the town at around 6:30 p.m. EST. It was near Interstate 95 where it overturned a truck, leaving two injured men and a kayak in a tree.

The town is drained by the Hampton Falls and Taylor rivers and is part of the Hampton River watershed leading to the Atlantic Ocean via Hampton Harbor. Of roughly 4,400 acres (18 km2) of salt marsh in the Seabrook-Hamptons Estuary, nearly 1,000 acres (4.0 km2) lie within Hampton Falls.
 The town is served by Interstate 95, U.S. Route 1, New Hampshire Route 84 and New Hampshire Route 88.

 Once a farming and lumbering community, the numerous falls on the Taylor River provided water power for mills operating within the town. Today it is largely residential, with numerous antique shops along U.S. 1. Applecrest Farm Orchards, established in 1913, is the town's largest employer, with 18 employees.
 Currently, the Lincoln Akerman School is the only public school in town. But at one point, five public schools existed, the North, South, West, and two East schools. One of the East Schools, founded around the time of the Civil War, burned down in 1947 when its furnace exploded, and the Lincoln Akerman School replaced it in 1949. While a new school was being built, students had to travel to the neighboring town of Seabrook, New Hampshire to attend school. The other East School was moved to an area near the new library. Another school was turned into a home, and another was crushed by a boulder one winter when students pushed it off a hill.
 High school students attend Winnacunnet High School in the neighboring town of Hampton.
 Heronfield Academy, a private Episcopal middle school, is located on Exeter Road on the border of Hampton Falls and Exeter.
