Central Jersey, or Central New Jersey, is the middle region of the U.S. state of New Jersey. The designation Central Jersey is a distinct administrative toponym.^[2][3] While New Jersey is often divided into North Jersey and South Jersey, many residents recognize Central Jersey as a distinct third entity.^[4] As of the 2020 census, Central Jersey has a population of 3,580,999.

All descriptions of Central Jersey include Middlesex County, the population center of New Jersey, and most include much of nearby Monmouth, Mercer, Somerset, and Hunterdon counties. The inclusion of adjacent areas of Union and Ocean are a source of debate.^[5][6][7] In 2015, New Jersey Business magazine defined Central Jersey more narrowly as the five counties of Hunterdon, Mercer, Middlesex, Monmouth and Somerset.^[8]

In 2022, legislation was proposed in the New Jersey Legislature to establish distinct geographic areas for tourism in the state. Bill A4711 was sponsored by Assemblymembers Roy Freiman, Sadaf Jaffer, and Anthony Verrelli in the New Jersey General Assembly.^[9] This included an official designation of the region of Central Jersey, which the legislation defines more broadly as the seven counties of Hunterdon, Mercer, Middlesex, Monmouth, Ocean, Somerset, and Union.^[10][11] The New Jersey Senate version of this legislation passed by a vote of 36-1 on June 20, 2023.^[12] On August 24, 2023, Gov. Murphy signed legislation officially designating Central Jersey including, at a minimum, the counties of Hunterdon, Mercer, Middlesex, and Somerset.^[13]

Trenton, the seat of Mercer County and the state capital of New Jersey, is located in Central Jersey. New Jersey's geographic center is in Hamilton, Mercer County. In 2011, the population center of the state was in the western portion of East Brunswick, in Middlesex County.^[14] The two busiest highways in New Jersey, the New Jersey Turnpike and the Garden State Parkway, intersect in Woodbridge, Middlesex County.^[15] Princeton University and Rutgers University, the two most prominent institutions of higher education in the state, are situated in Central Jersey.

The region lies roughly at the geographic heart of the Northeast megalopolis and is wholly in the New York metropolitan area, the nation's largest metropolitan area.

The Delaware Valley is another area that is associated with some parts of Central Jersey, specifically Mercer County. Yet despite the County’s close geographic proximity to Philadelphia's combined statistical area, Mercer County is considered part of the New York Combined Metropolitan Statistical Area as defined by the United States Census Bureau.^[16][17][18] Some but not all regions of Hunterdon County associate themselves with the Delaware Valley and the Philadelphia metropolitan area.

The Raritan Valley is the region along the middle reaches of the Raritan River and its North Branch and South Branch. The Raritan Valley includes the communities of Branchburg, Bridgewater, Somerville, Raritan, Hillsborough, Franklin Township, Green Brook, North Plainfield, Bound Brook, and South Bound Brook, all in Somerset County; Dunellen, Middlesex, Piscataway, South Plainfield, Highland Park, New Brunswick, East Brunswick, Edison, and Metuchen, all in the northern and central portions of Middlesex County; and Plainfield in southwestern Union County.^{[19][20][21][22][23]}

The Raritan Bayshore is used to describe the region in Middlesex and Monmouth Counties, located along the coastline of the Raritan Bay, from the mouth of the Raritan River in the west to the barrier island of Sandy Hook bordering the Atlantic Ocean in the east.^[24] The Raritan Bayshore includes the communities of Sayreville, Woodbridge, Perth Amboy, South Amboy, and Old Bridge, all in northeastern Middlesex County; Aberdeen, Matawan, Keyport, Union Beach, Hazlet, Keansburg, Holmdel, Middletown, Atlantic Highlands, and Highlands, all in northern Monmouth County.^[25][26]

Between 1674 and 1702, in the early part of New Jersey's colonial period, the border between West Jersey and East Jersey ran diagonally across the middle part of the state. The Keith Line, as the demarcation is known, ran through the center of what is now Mercer County.^[28] This border remained important in determining ownership and political boundaries until 1745. Remnants of that division are seen today, notably as the Hunterdon-Somerset, Ocean-Burlington, and Monmouth-Burlington county lines.^[29] The division of the two provinces was cultural as well as geographical.^[30]

New Jersey's position between the major cities of New York and Philadelphia led Benjamin Franklin to call the state "a barrel tapped at both ends".^[31][32] Travel between the two cities originally included a ferry crossing.

Due to the obstacles created by the Meadowlands and the Hudson Palisades, passengers from New York would cross the North River and the Upper New York Bay by boat and then transfer to stagecoaches to travel overland through what is now Central Jersey. One route from Elizabethtown to Lambertville was known as Old York Road. Another route, from Perth Amboy through Kingston to Burlington, ran along a portion of the Kings Highway, These roads followed Lenape paths known respectively as the Naritcong Trail and the Assunpink Trail.

Raritan Landing, across from New Brunswick in today's Piscataway, became an important inland port and commercial hub for the region.^[33] Two of the nine Colonial Colleges, founded before the American Revolution, were the College of New Jersey (now Princeton University), and Queens College (now Rutgers University).

All of the region's counties are ranked among the highest income counties in the United States, as measured by median household income.^[34] It has been called the state's "wealth belt".^[35][36]

For decades, Central Jersey was a hub for manufacturing in the eastern United States. Many industrial companies had major production facilities in and around the area, including Edison Assembly, Ford Motor Company's production plant for Rangers, Mustangs, Pintos, Mercurys, and Lincolns. Other notable companies include General Motors in Linden, Frigidaire's air-conditioner plant in Edison, Hess Corporation in Woodbridge, Siemens in Edison, and ExxonMobil Chemical.

Central New Jersey is a global leader in the pharmaceuticals industry. New Brunswick is known as "the Healthcare City",^[43][44] due to the concentration of medical facilities in Central Jersey, including Robert Wood Johnson University Hospital and Saint Peter's University Hospital, as well as the University of Medicine and Dentistry of New Jersey (UMDNJ)-Robert Wood Johnson Medical School. University Medical Center of Princeton is located in Plainsboro. The campuses of the major pharmaceutical corporations Bristol-Myers Squibb Company, Johnson & Johnson, Merck and Sanofi-Aventis are located in the region, as are major operations of Dr. Reddy's Laboratories and Aurobindo Pharma.

East Jersey Olde Towne Village, the Road Up Raritan Historic District as well as those in Trenton, Lawrence, and Princeton recall the colonial era. The region saw a lot of action during the American Revolution due to the region's strategic importance between Philadelphia and New York City.^[52] As such, many important battles took place here. These battle sites have been converted into state parks, offering historic preservation of the important structures contingent to their respected battles. State parks include Washington Crossing State Park, Princeton Battlefield State Park, and Monmouth Battlefield State Park.^[53] The Middlebrook encampment in Bridgewater was where the first official flag of the United States was unfurled, after a law to adopt a national flag had been passed by Congress on June 14, 1777.^[54] Ocean Grove is one of the largest national historic sites in the United States.

The Star-Ledger, based in Newark, is the largest circulated newspaper in New Jersey. Four Central Jersey newspapers, Asbury Park Press, Home News Tribune, and two Trenton dailies, The Trentonian and The Times and several local papers are published in Central Jersey. New Jersey On-Line, MyCentralJersey.com and CentralJersey.com^[55] are online news services. During statewide political events like Gubernatorial or Senatorial election debates often held in Trenton, partner stations from both the New York and Philadelphia markets pool resources together to co-host the events and bring them to New Jersey homes.

Identification with sports teams is also affected by the region's location, and it is not uncommon to find fans of major sports teams of either city. For example, while residents of northern New Jersey root for New York teams, those in the southern part of the state root for Philadelphia teams.^[56][57][58] The distinction is less clear in Central Jersey.^[59] Central Jersey Riptide was a short-lived professional soccer club.^[60]
