Hopkinton is a town in Middlesex County, Massachusetts, United States, 25 miles (40 km) west of Boston. The town is best known as the starting point of the Boston Marathon, held annually on Patriots' Day each April, and as the headquarters for the Dell EMC corporation.

At the 2020 census, the town had a population of 18,758. The U.S. Census recognizes the central village within the town as a census-designated place, with a population of 2,651 at the 2020 census. Hopkinton also includes the village of Woodville, which was established as a historic district in 2005.

The Town of Hopkinton was incorporated on December 13, 1715. Hopkinton was named for an early colonist of Connecticut, Edward Hopkins, who left a large sum of money to be invested in land in New England, the proceeds of which were to be used for the benefit of Harvard University. The trustees of Harvard purchased 12,500 acres of land from the Native American residents with money from the fund and incorporated the area, naming it in honor of its benefactor.

Grain was the first production crop grown in the area, while fruit and dairy industries were developed later. Agriculture predominated until 1840 when the boot and shoe industries were introduced into the town. By 1850 eleven boot and shoe factories were established in Hopkinton. Fires in 1882 and the migration of those industries to other parts of the country eliminated these industries from Hopkinton.

There are 215 Hopkinton properties listed in the State Register of Historic Places. The majority, 187, are located within the Cedar Swamp Archaeological District in Hopkinton and Westborough. The properties are also listed in the National Register of Historic Places.

Twenty-three properties are included within the Hopkinton Center Historic District, a local historic district which comprises properties around the Town Common, on East Main St. and the south side of Main St. The district was expanded in 2000 to include the Town Hall and in 2001 to include Center School. The Hopkinton Supply Company Building on Main St., located slightly west of the district, is listed in the National Register of Historic Places. Former factory worker housing in the center of town, contrasted against the more rural areas surrounding it, are visual reminders of Hopkinton's past.

In 2005, the town established a second historic district in the village of Woodville. The Woodville Historic District Commission was formed the same year. Ninety-seven properties are included within this district. The village of Woodville has retained its distinctive village atmosphere and strong architectural connection to Hopkinton's industrial development and growth from the mid-to-late 19th century. The area was an early cotton clothmaking center and the site of a major shoe factory. When Boston seized Lake Whitehall for its water supply in 1894, the factories along its shores were closed or moved to other sites, as they were considered sources of pollution. Remaining factories and other buildings were destroyed in a fire in 1909. In the 18th century, it was an agricultural area with a few farms scattered north of the much smaller Lake Whitehall and its accompanying cedar swamp, and was the site of a grist mill on Whitehall Brook as early as 1714.

Within or near the Miscoe-Warren-Whitehall Watersheds ACEC (Area of Critical Environmental Concern), remains of large pits have been found. The pits were lined with bark by the Native Americans and used to store corn over the winter months.

At one time, it was believed that the waters flowing from the large swamp south of Pond St., under Pond St. and into Lake Whitehall contained magical healing powers. As a result, the area quickly was built up as a resort area. Visitors came by stagecoach to the Hopkinton Hotel, which was located between Pond St. and the lake. The mineral baths and their powers lured the visitors to the area. The baths can still be viewed by the edge of the stream that drains from the swamp. Within the ACEC area are also two beehive shaped stone structures, about 6 feet (1.8 m) tall. Their origin and use are unknown.

Hopkinton gains national attention once a year in April as it hosts the start of the Boston Marathon, a role the town has enjoyed since 1924. The town takes pride in its hospitality as runners from all over the world gather in Hopkinton to begin the 26.2-mile (42.2 km) run to Boston. It is also a sister city of Marathon, Greece.

Hopkinton is in the southwestern corner of Middlesex County in eastern Massachusetts, 17 miles (27 km) east of Worcester, 26 miles (42 km) west of Boston, and 195 miles (314 km) from New York City. It is bordered by six towns:

North = Southborough Northeast = Ashland Southeast = Holliston South = Milford Southwest = Upton Northwest = Westborough

All but Ashland and Holliston are in neighboring Worcester County.

Hopkinton village is in the center of town, at the intersection of Main Street (Massachusetts Route 135) with Cedar Street/Grove Street (Massachusetts Route 85). The neighborhood of Woodville is in the western part of the town, along Route 135 at the north end of Whitehall Reservoir. Hopkinton State Park is in the northern part of the town, extending northeast into Ashland.

According to the United States Census Bureau, the town has a total area of 27.9 square miles (72.3 km), of which 26.2 square miles (67.9 km) are land and 1.6 square miles (4.1 km), or 5.85%, are water. Besides Whitehall Reservoir, notable water bodies include Hopkinton Reservoir in the north, in Hopkinton State Park, and North Pond and Echo Lake in the south. Whitehall Reservoir and Hopkinton Reservoir drain north to the Sudbury River, part of the Concord River watershed leading to the Merrimack River. North Pond, in the southwestern part of town, forms the headwaters of the Mill River, which flows south to join the Blackstone River in Rhode Island. Echo Lake, in the southeastern part of town, is at the headwaters of the Charles River, which flows east to Boston Harbor.

The climate in Hopkinton tends to be hot and humid during the summer, with daily high temperatures averaging in the 80s. Temperatures in the 90s are also known to occur between June and August as high-pressure air masses push in from the south. Winters are typical of areas inland and west of Boston. Snowfall averages around 45" but can vary tremendously from season to season.

Since its incorporation in 1715, Hopkinton has retained its original Open Town Meeting form of government. The town's day-to-day affairs had been directly overseen by an elected Board of Selectmen until 2007, when the Town's Charter Commission created a Town Manager position with more discretion, although the Town Manager still reports to the Select Board.

Hopkinton's Annual Town Meeting begins on the first Monday in May, hosted at the Hopkinton Middle School or High School. The meeting only begins when a quorum is formed, with 128 registered Hopkinton voters in attendance. It continues on consecutive evenings, usually three nights in total, until all articles in the Town Meeting Warrant have been voted upon.

The Town Meeting Warrant is a document composed of the articles to be voted upon. Any elected or appointed board, committee, or town officer, or ten petitioning voters, may request that an article be included on the warrant. Each article to be voted upon is directed by the Select Board to an appropriate board or committee to hear and provide the original motion at Town Meeting. All articles which require expending of funds are directed to the Finance Committee; articles dealing with planning and zoning to the Planning Board; articles relating to by-laws to the By-Law Committee, and so forth.

Hopkinton Annual Town Election is held on the third Monday in May. Polls are open 7:00am–8:00pm. All Hopkinton precincts vote at the Hopkinton Middle School.

The Hopkinton Public Library was founded in 1867. It has been located in the heart of downtown, just steps away from the Town Common, since 1895. Until 1955, bequests were the only source of funding for the library. Since that time, the town government has been appropriating public funds for employee salaries, cost of cleaning the Library, utilities and assistance with the purchase of books. The library is now funded through various sources that include the Town Government, The McGovern Trust Fund, Annual State Aid and Friends of the Library.

The town library was established by the Young Men's Christian Association in 1867. Seven members served as the Trustees, incorporated the Library and adopted by-laws for the government of the Library in 1890. The current building was built in 1895 with contributions from local and former residents of Hopkinton. The second floor was used as a lecture hall and was remodeled later as a children's room. A gallery was built to connect the Library building with the adjacent Episcopal Church after extensive renovation in 1967. This new section was named after the head librarian at the time, Mrs. Betty Strong. A special feature of the reading room is a stained glass window with a motif of water fountain bubbling water flowing over an open book and the inscription on the page reads "The fountain of wisdom flows through books." The large hall clock that still stands near the circulation desk was presented to the Library by Mrs. F.V. Thompson and Mr. Abram Crooks.

The library was transferred to the town government in May 2010. Five members were appointed as the Library Trustees. Starting from May 2011, elections have been held annually for the members of the Library Board according to the new town charter.

In January 2016, the library announced they would make renovations to the building and moved to a temporary location at 65 South Street while the historic building on Main Street undergoes a major renovation and expansion.

In October 2017, the renovated and expanded library reopened in its downtown location at 13 Main Street.

The Town of Hopkinton has a public school system which serves students from pre-kindergarten through twelfth grade. Kindergarten students and first-graders attend Marathon Elementary School. Grades 2 and 3 attend Elmwood School. Grades 4 and 5 attend Hopkins School. Grades 6 through 8 attend Hopkinton Middle School. Grades 9 through 12 attend Hopkinton High School. The town also has an integrated preschool currently located in the Marathon Elementary School building.

Hopkinton offered a fee-based full-day kindergarten option for the first time during the 2010–2011 school year via a lottery system. Free full-day Kindergarten was made available to all Kindergarten students starting in the 2014–2015 school year. Hopkinton Public Schools does not offer any foreign language education before Grade 7.

Since residents approved the Center School Feasibility Study in May 2008, Hopkinton had been involved in an Elementary School Building Project with the Massachusetts School Building Authority. The solution approved unanimously by the Hopkinton Elementary School Building Committee and the MSBA was to build a new K–5 Elementary School on the town-owned Fruit Street property and then decommission the aging Center School. Residents voted down the new school at the March 21, 2011, Special Town Meeting and again at a Special Town Election on March 28, 2011.

In May 2013 voters approved funding a new Center School Feasibility Study. The solution proposed by the new Elementary School Building Committee was to build a new Preschool, Kindergarten and Grade 1 School at 135 Hayden Rowe Street (Route 85), on property newly purchased by the town for this purpose. This proposal was approved by voters at a November 2015 Special Town Meeting. The new Marathon Elementary School, named after a public town survey, is located on Route 85 in Hopkinton, and opened for the fall 2018 school year.

Hopkinton High's school mascot is the Hiller "H", as the sports teams are known as the Hopkinton Hillers. Previously the teams were known as the Hopkinton Stonethrowers. The school primary colors are green and white, with orange as a secondary color.
