Hillsborough Township is a township in Somerset County, in the U.S. state of New Jersey. Located in the Raritan Valley region, the township is a suburban and exurban bedroom community of New York City within the New York Metropolitan Area. As of the 2020 United States census, the township's population was 43,276, an increase of 4,973 (+13.0%) from the 2010 census count of 38,303, which in turn reflected an increase of 1,669 (+4.6%) from the 36,634 counted in the 2000 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Hillsborough Township was originally created by Royal charter issued May 31, 1771, which was revoked and revised on September 12, 1771.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.

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.

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 (6.04Â km) US 206 Bypass began in 2010 to bypass the congested stretch of the road. Built in two phases, the first 1.66-mile (2.67Â 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 (16.48Â km) through the township, and CR 533.
