Hillsborough Township is a township in Somerset County, New Jersey, United States. The township is centrally located in the Raritan Valley region within the much larger New York Metropolitan Area. As of the 2010 United States Census, the township's population was 38,303, reflecting an increase of 1,669 (+4.6%) from the 36,634 counted in the 2000 Census, which had in turn increased by 7,826 (+27.2%) from the 28,808 counted in the 1990 Census.
Hillsborough Township was originally created by Royal charter issued May 31, 1771, which was revoked and revised on September 12, 1771. It was incorporated on February 21, 1798 by the New Jersey Legislature Township Act of 1798 as one of New Jersey's original group of 104 townships. Portions of the township were taken to form the boroughs of Millstone (May 14, 1894) and Manville (April 1, 1929). The township's name may have come from an earlier name of "Hillsbury", though it may have been named for Wills Hill, 1st Marquess of Downshire who was the Earl of Hillsborough.
On May 31, 1771, Hillsborough was officially granted a Charter incorporating it as a Township. A revised charter was issued on September 12, 1771. The records of Hillsborough Township are complete from their inception in 1746 and there are ten volumes, each some several hundred pages, kept in the Special Collections Department of the Rutgers University Library along with the Charter.
Hillsborough Township quickly took its place in history as the path General George Washington and his troops traveled from the Battle of Princeton to winter quarters in Morristown. While the British were encamped in the valley below awaiting an opportunity to attack, it is said that Washington drilled his troops on the Sourland Mountain around a spring near the top using different formations and corn stalks for guns. As the sun caught the stalks, the British thought Washington had received reinforcements and fresh supplies. The British troops, thinking that they were outnumbered, slipped off to New Brunswick leaving Washington to continue to Morristown.
The township was formally incorporated on February 21, 1798.
Hillsborough is the home of the Belle Mead GSA depot, or Belle Mead General Depot, which was a storage site for materials during World War II, along with housing Italian and German prisoners of war. It continued storing materials until the 1980s, and various contaminants have leaked into the ground and surrounding area during that time. Efforts are under way to convert the site into a mixed recreation and R&D complex.
Hillsborough is home to Duke Gardens and Duke Farms, a 2,700 acres (11 km2) estate in the north-eastern quadrant of the town that was originally owned by tobacco and electric energy tycoon James "Buck" Duke and then passed down to daughter Doris Duke, and is now one of the few remaining "preserved" natural areas in Hillsborough Township.
In Money magazine's 2013 Best Places to Live rankings, Hillsborough was ranked 16th in the nation, the third-highest among the three places in New Jersey included in the top 50 list. In the magazine's 2007 rankings, the township was ranked as the 23rd best place to live in the nation.
According to the United States Census Bureau, the township had a total area of 55.10 square miles (142.71 km2), including 54.61 square miles (141.45 km2) of land and 0.49 square miles (1.26 km2) of water (0.88%).

Duke Farms is an estate that was established by James Buchanan Duke, an American entrepreneur who founded Duke Power and the American Tobacco Company. The property is managed by the Doris Duke Foundation after the death of Doris Duke, the second owner. After extensive reorganization and an investment of $45 million, "Duke Farms" was opened to the public on May 19, 2012. Duke Farms is owned by the Duke Farms Foundation (DFF) that was established in 1998 to manage the estate. The Foundation, in turn, is part of the Doris Duke Charitable Foundation, and the two entities share a common board and leadership team.
Despite some controversy for when the commission made the decision to permanently close Duke Gardens, demolishing the indoor display gardens that had been created by Doris Duke, the commission has made strides in contributing to renovating the property for the 21st century. The DFF over the years have created new indoor and outdoor display gardens that are eco-friendly, use native plants, and are wheelchair accessible. In the process of rehabilitation numerous invasive foreign plants were removed including Norwegian maple and Asian Ailanthus and replaced by native species. On May 19, 2012, Duke Farms opened to the public. After a $45-million renovation, Duke Farms now include 30 endangered species and 230 varieties of birds, among which are the great blue heron and the bald eagle. As part of the rehabilitation, the conservatory and greenhouses known as the Orchid Range were renovated to became more energy-efficient.
Hillsborough Township is governed under the Township form of New Jersey municipal government, one of 141 municipalities (of the 564) statewide that use this form, the second-most commonly used form of government in the state. The Township Committee is comprised of five members, who are elected directly by the voters at-large in partisan elections to serve three-year terms of office on a staggered basis, with either one or two seats coming up for election each year as part of the November general election in a three-year cycle. The mayor and deputy mayor are chosen by the Township Committee from among its members at an annual reorganization meeting, each serving a one-year term.
As of 2022[update], members of the Hillsborough Township Committee are Mayor Shawn Lipani (R, term on committee ends December 31, 2024; term as mayor ends 2022), Deputy Mayor Janine Erickson (R, term on committee ends 2023; term as deputy mayor ends 2022), Robert Britting (R, 2024; appointed to serve an unexpired term), Frank DelCore (R, 2022) and Douglas Tomson (R, 2023).
In March 2022, the Township Committee selected Robert Britting from three names nominated by the Republican municipal committee to fill the seat expiring in December 2024 that had been held by Steven Cohen until he stepped down from office due to COVID-19-related health issues. Britting will serve on an interim basis until the November 2022 general election, when voters will choose a candidate to serve the balance of the term of office.
In March 2021, the Township Committee chose Democrat Jeffrey Wright from three candidates listed by the local Democratic committee to fill the seat expiring in December 2021 that had been held by Olivia Holmes, who had resigned the previous month due to COVID related issues.

The Hillsborough Township School District serves students in pre-kindergarten through twelfth grade. Students from Millstone attend the district's schools, originally as part of a sending/receiving relationship; the New Jersey Commissioner of Education merged Millstone's non-operating school district with the Hillsborough Township School District effective July 1, 2009. As of the 2020–2021 school year, the district, comprised of nine schools, had an enrollment of 7,288 students and 596.6 classroom teachers (on an FTE basis), for a student–teacher ratio of 12.2:1. Schools in the district (with 2020–2021 enrollment data from the National Center for Education Statistics) are Amsterdam Elementary School (456 students; in grades K–4), Hillsborough Elementary School (488; K–4), Sunnymead Elementary School (495; K–4), Triangle Elementary School (354; K–4), Woodfern Elementary School (354; K–4), Woods Road Elementary School (421; Pre-K–4), Auten Road Intermediate School (1,143; 5–6), Hillsborough Middle School (1,218; 7–8) and Hillsborough High School (2,318; 9–12).
Roads and highways
As of May 2010[update], the township had a total of 211.92 miles (341.05 km) of roadways, of which 185.42 miles (298.40 km) were maintained by the municipality, 19.79 miles (31.85 km) by Somerset County and 6.71 miles (10.80 km) by the New Jersey Department of Transportation.
U.S. Route 206 is the main road that passes through the township. Construction of a new alignment of US 206, the 3.75-mile (6.04 km) US 206 Bypass began in 2010 to bypass the congested stretch of the road. Built in two phases, the first 1.66-mile (2.67 km) phase, between Hillsborough and Amwell Roads, was opened in October 2013. The second phase was originally expected to be completed by 2015, but was delayed multiple times due to a lack of state funding. Construction finally resumed in 2017 and the roadway was completed in 2021. The road is named for Peter J. Biondi, a former Hillsborough mayor and member of the General Assembly.
Now that construction of the Bypass is completed, the intention is for the existing US-206 to become a downtown "main street" for the township and be zoned for commercial and residential use.
Main county roads that pass through are CR 514 which runs for 10.24 miles (16.48 km) through the township, and CR 533. Interstate 287 is outside the municipality in bordering Bridgewater and Franklin Townships. Part of the proposed routing of Interstate 95 through central New Jersey included Hillsborough; this project was ultimately canceled in the 1980s.
NJ Transit has proposed a new West Trenton Line that would stretch for 27 miles (43 km) from the West Trenton station in Ewing Township to a connection with the Raritan Valley Line at Bridgewater Township, and from there to Newark Penn Station in Newark. The plan would include stations at both Belle Mead and Hillsborough. The plan was canceled due to lack of funding and NJ Transit has no plans to restore the project.
Coach USA offers weekday express service across 42nd Street to the United Nations in Midtown Manhattan from Hillsborough operated by Suburban Transit. There are four morning buses Monday through Friday with a reduced schedule on some Holidays.
