Middlesex County is a county located in north-central New Jersey, United States. In 2018, the Census Bureau estimated the county's population at 829,685, making it the state's second-most populous county, an increase of 4.1% from 809,858 in the 2010 census. Middlesex is part of the New York metropolitan area, and its county seat is New Brunswick. The center of population of the state of New Jersey is located in Middlesex County, in East Brunswick Township, just east of the New Jersey Turnpike. The 2000 Census showed that the county ranked 63rd in the United States among the wealthiest counties by median household income. The Bureau of Economic Analysis ranked the county as having the 143rd-highest per capita income of all 3,113 counties in the United States (and the 10th-highest in New Jersey) as of 2009. Middlesex County holds the nickname, The Greatest County in the Land.
The county was primarily settled due to its ideal location near the Raritan River and was established as of March 7, 1683, as part of the Province of East Jersey and was partitioned as of October 31, 1693, into the townships of Piscataway, Perth Amboy, and Woodbridge. Somerset County was established on May 14, 1688, from portions of Middlesex County. The county's first court met in June 1683 in Piscataway, and held session at alternating sites over the next century in Perth Amboy, Piscataway, and Woodbridge before relocating permanently to New Brunswick in 1778. Middlesex County hosts an extensive park system totaling more than 6,300 acres (2,500 ha).
According to the 2010 Census, the county had a total area of 322.83 square miles (836.1 km2), including 308.91 square miles (800.1 km2) of land (95.7%) and 13.91 square miles (36.0 km2) of water (4.3%). The county is named after the historic English county of Middlesex.
Bisected by the Raritan River, the county is topographically typical of Central Jersey in that it is largely flat. The elevation ranges from sea level to 300 feet (91 m) above sea level on a hill scaled by Major Road/ Sand Hill Road near Route 1 in South Brunswick Township.

Middlesex County is governed by a Board of Chosen Freeholders, whose seven members are elected at-large on a partisan basis to serve three-year terms of office on a staggered basis, with either two or three seats coming up for election each year as part of the November general election. At an annual reorganization meeting held in January, the board selects from among its members a Freeholder Director and Deputy Director. The Freeholder Director appoints Freeholders to serve as Chairpersons and members on the various committees which oversee county departments. Middlesex County also elects three "constitutional officers" whose existence is laid out in the New Jersey Constitution. The County Clerk and Surrogate serve five-year terms and the Sheriff serves a three-year term of office. In 2016, freeholders were paid $23,438 and the freeholder director was paid an annual salary of $24,428, though Ronald Rios has accepted a salary of $8,340 as director.
Article VII Section II of the New Jersey State Constitution requires each county in New Jersey have three elected administrative officials known as "constitutional officers."

As of March 23, 2011, there were a total of 455,044 registered voters in Middlesex County, of which 169,718 (37.3%) were registered as Democrats, 57,711 (12.7%) were registered as Republicans and 227,355 (50.0%) were registered as Unaffiliated. There were 260 voters registered to other parties.
After being a Republican stronghold in the late 19th and early 20th centuries, Middlesex County leaned Democratic for much of the 20th century beginning with Franklin Roosevelt's victory in the county in 1932. Throughout the twentieth century, in close elections the county would always vote Democratic, sometimes by solid margins, but the county was willing to flip Republican in the midst of nationwide Republican landslides in the 1970s and 80s. However, since the 1990s, Middlesex County has become a Democratic stronghold at the national level, mirroring the state's heavy swing to the Democrats.
Democrat Bill Clinton carried the county in 1992 and it has remained reliably blue in every election since. In the nationally close 2000 election, Democrat Al Gore won the county decisively with 59.9% of the vote to Republican George W. Bush's 36.1%, a Democratic victory margin of 23.7%, while winning the state overall by a 56-40 margin. In the 2004 U.S. Presidential election, many of the suburban counties surrounding New York City, including Middlesex County, swung Republican in response to the 9/11 terrorist attacks, but Democrat John Kerry still carried the county comfortably by a 13.6% margin over George W. Bush, Kerry taking 56.3% of the vote to Bush's 42.8%, while Kerry carried the state overall by 6.7% over Bush. In 2008, Barack Obama carried Middlesex County by a much larger 21.8% margin over John McCain, Obama taking 60.2% of the vote to McCain's 38.4%, while Obama won New Jersey overall by 15.5% over McCain. In 2012, Obama won an even more commanding victory in the county, receiving 63.2% of the vote to Republican Mitt Romney's 35.6%, a Democratic victory margin of 27.6%, while carrying New Jersey overall by 17.8%. Like much of the New York City metro area, Middlesex County was one of the few parts of the country to actually swing even harder in Obama's favor in 2012 compared to 2008, even as he lost ground nationally, indicating a long-term trend toward Democratic dominance in Middlesex County.
In the 2005 Gubernatorial Election, the county went to Democrat Jon Corzine by a 56-39 margin; while in the 2009 Gubernatorial Election, Republican Chris Christie received 47% of the vote, defeating incumbent Democrat Corzine, who received around 45%.
Thomas N. Acken served as the sheriff in 1891. Joseph Spicuzzo served in 2014 and was arrested for bribery. Mildred S. Scott is the current sheriff.

The county also includes some limited access highways and Interstates as well. Middlesex County hosts the southern end of the Middlesex Freeway (Interstate 287) which then turns into Route 440 that connects to the Outerbridge Crossing. The Garden State Parkway passes through the eastern edge of the county, which features nine interchanges and the northern start/end of the split-roadways (Express & Local Lanes). The New Jersey Turnpike carries Interstate 95 through the center of the county. The Turnpike has five interchanges in Middlesex County: Exit 12 in Carteret, Exit 11 in Woodbridge Township, Exit 10 in Edison, Exit 9 in East Brunswick and Exit 8A in Monroe Township.
The Turnpike Authority planned to build Route 92, which was to start near the intersection of Ridge Road & Route 1 in South Brunswick Township to Interchange 8A in Monroe Township. This plan was cancelled on December 1, 2006.
The southern end of the "dual-dual" configuration (inner car lanes and outer truck lanes) used to be one mile south of Interchange 8A at the border of Cranbury Township and Monroe Township. It was relocated to Exit 6 in Mansfield Township in Burlington County after the Turnpike widening project was completed in early November 2014.
NJ Transit provides Middlesex County with frequent commuter rail service along the North Jersey Coast Line, Northeast Corridor Line, and Raritan Valley Line. The North Jersey Coast Line runs through the eastern part of the county. The Northeast Corridor Line runs through the northern and central part of the county. The Raritan Valley Line serves Dunellen and is accessible to other communities along the county's northern border with Union and Somerset counties.
Intercity rail service is provided by Amtrak. The routes that run through Middlesex County are the Acela Express, Keystone, Northeast Regional, and Vermonter services, although only the Keystone and Northeast Regional have regular stops within Middlesex County, at either New Brunswick or Metropark station. The Acela service also occasionally stops at Metropark.
Bus service in Middlesex County is provided by New Jersey Transit, Coach USA's Suburban Transit, the extensive Rutgers Campus bus network, the MCAT shuttle system, and DASH buses. There are bus routes that serve all townships in the county on weekdays, and studies are being conducted to create the New Brunswick Bus Rapid Transit system.
