Mont Vernon broke away from neighboring Amherst in 1803, following a dispute over the town parish. It later added a small portion of neighboring Lyndeborough.^[5]

Mont Vernon's general history follows that of many towns in this region. Originally settled for agriculture, its farms were hard hit after the Civil War when railroads opened up better farming land in the Midwest. The town's population peaked in 1870 and began to decline.

By the late 1890s, it had become a tourist town, drawing summer visitors from points south, notably Boston, who escaped the heat in Mont Vernon's hills. At one point, it had five large summer hotels, including the Grand Hotel, located on top of Grand Hill.

The hotel business began to wither with the development of the automobile, which allowed tourists to reach places like the White Mountains of New Hampshire, and it was killed by the Great Depression. The town's population bottomed out at barely 300 in 1930, at which time the Grand Hotel was destroyed in a fire. The remaining hotels were torn down before World War II.

Since the war, Mont Vernon has slowly become a suburban community. This was significantly accelerated in 1962–1963 when engineers and technicians employed at Sanders Associates in Nashua found homes in Mont Vernon attractive. It wasn't until the 1970 census that the town's official population passed mid-19th century highs.

Agriculture, including a 1940s and 1950s boom in chicken and egg farming, has all but disappeared. As of 2019, the town has one dairy farm. The town has one general store that except for a two-year period from 2010–2012 has operated for more than 120 years in the same location.^[6]

Mont Vernon made national news in March 2012 due to debate during the annual town meeting over whether to rename a small fishing hole called Jew Pond.^[7] The town eventually renamed it Carleton Pond, after the family which donated the surrounding property to the town.^[8]

Mont Vernon had a private school that started as the Appleton Academy in 1853 and was renamed the McCollom Institute in 1871, which closed shortly before the turn of the century. The building was used as a public high school for a few years, and later became the private Stearns School, which operated from 1906 to 1937, when it closed its doors due to low enrollment during the Great Depression. The building was later used for a public elementary school and now houses the police department and town offices.^[12]

The former two-story Mont Vernon Fire Station, built in 1947, was located on North Main Street next to the Town Hall. This station had 6 apparatus bays. In March 2007 the town voted to raze the deteriorating building and replace it with a new fire station on the same lot. The new station has 5 apparatus bays facing North Main Street, and 1 bay facing Pinkham Avenue. The Fire Chief has his office in the station, along with a radio and report room, a meeting room, and an office for the Emergency Management Director. The station also contains maintenance, storage, and work rooms. Emergency medical services are provided by Amherst.^[13]

The town has two major annual celebrations: On the last Saturday in September, it hosts "Lamson Farm Day" at a town-owned farm to celebrate its agricultural past. In late April or early May, it has a celebration of spring called the "Mont Vernon Spring Gala". Both feature games, food and local entertainers.

The town has two sports teams that compete regionally. They are the Mont Vernon Falcons basketball team and the Mont Vernon Acers volleyball team. Both teams are for girls age 9–12. The Mont Vernon Village School (grades K–6) has a basketball court and volleyball court. Adult volleyball has been playing on Monday nights at the school since the early 1990s. The town owns land near the school that has a baseball field with bases, fencing and two dugouts. The adjacent field is also used for many other sports. Golf was played behind what is now the site of the post office is in the early 1900s.

There is a gun sporting range in town (the Purgatory Falls Fish & Game Club), and local hunting can be widely found in the fall. There was a ski hill with a rope tow that disbanded in the middle of the 20th century. Mont Vernon is known for views over the Souhegan Valley and has hiking trails, especially in town-owned Lamson Farm and along Purgatory Brook, which forms most of its western border.
