Mercer County is a county located in the U.S. state of New Jersey. Its county seat is Trenton, also the state capital, prompting its nickname The Capital County. Mercer County alone constitutes the Trenton–Princeton metropolitan statistical area and is considered part of the New York combined statistical area by the U.S. Census Bureau, but also directly borders the Philadelphia metropolitan area and is included within the Federal Communications Commission's Philadelphia Designated Media Market Area.
As of the 2020 United States census, the county retained its position as the state's 12th-most-populous county, with a population of 387,340, its highest decennial count ever and an increase of 20,827 (+5.7%) from the 366,513 recorded at the 2010 census, which in turn had reflected an increase of 15,752 (+4.5%) from the 350,761 enumerated at the 2000 census The most populous municipality in Mercer County at the 2020 census was Hamilton Township, with 92,297 residents, while Hopewell Township was the largest in area.
The county was formed by an act of the New Jersey Legislature on February 22, 1838, from portions of Burlington County (Nottingham Township, now Hamilton Township), Hunterdon County (Ewing Township, Lawrence Township, Trenton, and portions of Hopewell Township), and Middlesex County, (West Windsor Township and portions of East Windsor Township). The former Keith Line bisects the county and is the boundary between municipalities that previously had been separated into West Jersey and East Jersey.
Trenton–Mercer Airport in Ewing Township is a commercial and corporate aviation airport serving Mercer County and its surrounding vicinity. The official residence of the governor of New Jersey, known as Drumthwacket, is located in Princeton, and is listed on both the U.S. National Register of Historic Places and the New Jersey Register of Historic Places. Mercer County contains 12 municipalities, the fewest of any county in New Jersey, and equal to Hudson County. The county is located in the Central Jersey region.
The county was named for Continental Army General Hugh Mercer, who died as a result of wounds received at the Battle of Princeton on January 3, 1777. Continental Army Brigadier General Hugh Mercer served in the Continental Army during the Battle of Trenton and the Battle of Princeton in 1777. A Scotsman that fled to British North America after the failed Jacobite Rebellion, he worked closely with George Washington in the American Revolution. On January 3, 1777, Washington's army was en route to Princeton, New Jersey. While leading a vanguard of 350 soldiers, Mercer's brigade encountered two British regiments and a mounted unit. A fight broke out at an orchard grove and Mercer's horse was shot from under him. Getting to his feet, he was quickly surrounded by British troops who mistook him for George Washington and ordered him to surrender. Outnumbered, he drew his saber and began an unequal contest. He was finally beaten to the ground, bayoneted repeatedly (seven times), and left for dead. Legend has it that a beaten Mercer, with a bayonet still impaled in him, did not want to leave his men and the battle and was given a place to rest on a white oak tree's trunk, and those who remained with him stood their ground. The Mercer Oak, against which the dying general rested as his men continued to fight, appears on the county seal and stood for 250 years until it collapsed in 2000.
Founded February 22, 1838, from portions of surrounding counties, Mercer County has a historical impact that reaches back to the pivotal battles of the American Revolutionary War. On the night of December 25–26, 1776, General George Washington led American forces across the Delaware River to attack the Hessian forces in the Battle of Trenton on the morning of December 26, also known as the First Battle of Trenton. Following the battle, Washington crossed back to Pennsylvania. He crossed a third time in a surprise attack on the forces of General Charles Cornwallis at the Battle of the Assunpink Creek, on January 2, 1777, also known as the Second Battle of Trenton, and at the Battle of Princeton on January 3. The successful attacks built morale among the pro-independence colonists. Ewing Church Cemetery in Ewing is one of the oldest cemeteries in the area, having served the Ewing community for 300 years. It is home to the burial places of hundreds of veterans from The Revolutionary War to the Vietnam War.
Since 1790, Trenton has served as the state's capital, earning the county the name "the Capitial County." After the Legislature relocated to Trenton from Perth Amboy in 1790, it purchased land for £250 and 5 shillings and constructed a new state house, designed by Philadelphia-based architect Jonathan Doane, beginning in 1792. The Doane building was covered in stucco, measured 150 by 50 feet (46 by 15 m), and housed the Senate and Assembly chambers in opposite wings. To meet the demands of the growing state, the structure was expanded several times during the 19th century. New Jersey, along with Nevada, is the only state to have its capital be located at the border with another state, as Trenton across the Delaware River from Pennsylvania.
The county experienced rapid urbanization and population growth during the first half of the 20th century due to the growth of industrialization in places such as the city of Trenton. Mercer County has the distinction of being the famed landing spot for a fictional Martian invasion of the United States. In 1938, in what has become one of the most famous American radio plays of all time, Orson Welles acted out his The War of the Worlds invasion. His imaginary aliens first "landed" at what is now West Windsor Township. A commemorative monument is erected at Grover's Mill park.
There were 27 Mercer County residents killed during the September 11, 2001 terrorist attacks in Lower Manhattan. A 10-foot (3.0 m) long steel beam weighing one ton was given to the county by the Port Authority of New York and New Jersey in March 2011 and is now displayed at Mercer County Park.
Geography and climate
According to the U.S. Census Bureau, as of the 2020 Census, the county had a total area of 228.86 square miles (592.7 km2), of which 224.44 square miles (581.3 km2) was land (98.1%) and 4.42 square miles (11.4 km2) was water (1.9%).
The county is generally flat and low-lying on the inner coastal plain with a few hills closer to the Delaware River. Baldpate Mountain, near Pennington, is the highest hill, at 480 feet (150 m) above sea level. The lowest point is at sea level along the Delaware River.
Most of Mercer has a hot-summer humid continental climate (Dfa) except for the southern portion of the county near and including Trenton where a humid subtropical climate (Cfa) exists. The hardiness zones are 6b and 7a.

Roads and highways
Mercer County has county routes, state routes, U.S. Routes and Interstates that all pass through. As of 2010[update], the county had a total of 1,524.30 miles (2,453.12 km) of roadways, of which 1,216.48 miles (1,957.73 km) were maintained by the local municipality, 175.80 miles (282.92 km) by Mercer County, 118.99 miles (191.50 km) by the New Jersey Department of Transportation, 1.19 miles (1.92 km) by the Delaware River Joint Toll Bridge Commission and 12.43 miles (20.00 km) by the New Jersey Turnpike Authority.
The county roads that traverse through are NJ County Route 518 (only in the Hopewells), NJ County Route 524, County Route 526, NJ County Route 533, NJ County Route 535, NJ County Route 539, NJ County Route 546, NJ County Route 569, NJ County Route 571, and NJ County Route 583.
The state routes that pass through Mercer are NJ Route 27 (only in Princeton), NJ Route 29, NJ Route 31, NJ Route 33, NJ Route 129, and NJ Route 133 (only in East Windsor). There are three U.S. Routes that pass through Mercer County: U.S. Route 1, which bisects the county, U.S. Route 130, and U.S. Route 206.
Mercer County houses a few limited access roads, such as Interstate 295, Interstate 195, and the New Jersey Turnpike (Interstate 95). (Mercer is the only county in the state that hosts I-95 and both its auxiliary routes.) I-295 functions as a partial ring-road around the Trenton area, while I-195 serves as an east–west expressway from Trenton to the Jersey Shore. The Turnpike (I-95) passes through the southeastern section of the county, and serves as a major corridor to Delaware, Washington, D.C. to the south, and New York City and New England towards the north. Two turnpike interchanges are located within Mercer County: Exit 7A in Robbinsville Township and Exit 8 in East Windsor Township.
Before 2018, Interstate 95 abruptly ended at the interchange with US 1 in Lawrence Township, and became I-295 south. Signs directed motorists to the continuation of I-95 by using I-295 to I-195 east to the New Jersey Turnpike. This was all due in part to the cancellation of the Somerset Freeway that was supposed to go from Hopewell Township in Mercer County up to Franklin Township in Somerset County.
The section of I-95 west of the US 1 interchange in Lawrence was re-numbered as part of I-295 in March 2018, six months before a direct interchange with Interstate 95 in Pennsylvania and the Pennsylvania Turnpike opened. This planned interchange indirectly prompted another project: the New Jersey Turnpike Authority extended the 'dual-dual' configuration (inner car lanes and outer truck / bus / car lanes) to Interchange 6 in Mansfield Township, Burlington County from its former end at Interchange 8A in Monroe Township, Middlesex County. This widening was completed in early November 2014.
Mercer hosts several NJ Transit stations, including Trenton, Hamilton and Princeton Junction on the Northeast Corridor Line, as well as Princeton on the Princeton Branch. SEPTA provides rail service to Center City Philadelphia from Trenton and West Trenton. Long-distance transportation is provided by Amtrak train service along the Northeast Corridor through the Trenton Transit Center.
NJ Transit's River Line connects Trenton to Camden, with three stations in the county, all within Trenton city limits, at Cass Street, Hamilton Avenue and at the Trenton Transit Center.
Mercer County's only commercial airport, and one of three in the state, is Trenton–Mercer Airport in Ewing Township, which is served by Frontier Airlines, offering nonstop service to and from points nationwide.
