Monmouth County (/ˈmɒnməθ/) is a county located on the coast of New Jersey, in the United States within the New York metropolitan area, and the northernmost county along the Jersey Shore. As of the 2019 Census estimate, the county’s population was 618,795, making it the state’s fifth-most populous county, representing a decrease of 0.6% from the 2010 Census, when the population was enumerated at 630,380, in turn an increase of 15,079 from 615,301 at the 2000 Census. As of 2010, the county fell to the fifth-most populous county in the state, having been surpassed by Hudson County. Its county seat is Freehold Borough. The most populous place was Middletown Township, with 66,522 residents at the time of the 2010 Census, while Howell Township covered 61.21 square miles (158.5 km2), the largest total area of any municipality.
In 1609, the English navigator, Henry Hudson, and his crew aboard the Dutch vessel Half Moon spotted land in what is now Monmouth County, most likely off Sandy Hook; however, some historical accounts credit this landing to present-day Keansburg. Among the first European settlers and majority landowners in the area were Richard and Penelope Stout. Penelope “miraculously” survived her wounds from a native attack in Sandy Hook and further lived to the age of 110. Additionally, a group of Quaker families from Long Island settled the Monmouth Tract, an early land grant from Richard Nicolls issued in 1665. They were followed by a group of Scottish settlers who inhabited Freehold Township in about 1682–85, followed several years later by Dutch settlers. As they arrived in this area, they were greeted by Lenape Native Americans, who lived in scattered small family bands and developed a largely amicable relationship with the new arrivals. Enslaved Africans were present in the area from at least 1680, and by 1726 made up 9% of the total population of the county.
Monmouth County was established on March 7, 1683, while part of the province of East Jersey. On October 31, 1693, the county was partitioned into the townships of Freehold, Middletown and Shrewsbury. Its name may come from a suggestion from Colonel Lewis Morris that the county should be named after Monmouthshire in Wales, Great Britain. Other suggestions include that it was named for James Scott, 1st Duke of Monmouth (1649–1685), who had many allies among the East Jersey leadership. In 1714, the first county government was established.
At the June 28, 1778, Battle of Monmouth, near Freehold Township, General George Washington‘s soldiers battled the British under Sir Henry Clinton, in the longest land battle of the American Revolutionary War. It was at Monmouth that the tactics and training from Friedrich Wilhelm von Steuben developed at Valley Forge during the winter encampment were first implemented on a large scale.
At independence, Monmouth’s population included 1,640 slaves, as well as an undetermined number of free African Americans. The number of enslaved persons fell steeply after 1820, though a small number remained until at least 1850. Monmouth’s free African American population climbed from 353 in 1790 to 2,658 in 1860. There was a small African-American middle class consisting of freedmen present in Monmouth County by the 1840s and 1850s.
Ocean County was carved out of Monmouth County in 1850.
In 1790 Monmouth County’s population was 16,918, of whom roughly 6,600 were of English descent and the remainder were Welsh, Dutch and Swedish, as well as small amounts of African Americans and Northern Irish Protestants. By the year 2010 Monmouth County’s population was 628,112 of whom 40,489 were of English descent. Between 1890 and 1907 nearly 18 million European immigrants came to America. At the same time the region underwent massive and not unrelated economic changes, this process led to places like Monmouth County, New Jersey becoming significantly more diverse and somewhat less rural.
According to the 2010 census, the county had a total area of 665.32 square miles (1,723.2 km2), including 468.79 square miles (1,214.2 km2) of land (70.5%) and 196.53 square miles (509.0 km2) of water (29.5%).
Much of Monmouth County remains flat and low-lying even far inland. However, there are some low hills in and around Holmdel Township, and one of them, Crawford Hill, the former site of a radar facility, is the county’s highest point, variously listed at 380 to 391 feet (116 to 119 m) above sea level. The top portion of the hill is owned by Alcatel-Lucent and houses a research laboratory of Bell Laboratories. The northeastern portion of the county, in the Locust section of Middletown Township and the boroughs of Highlands and Atlantic Highlands, are also very hilly. The lowest point is sea level.
Along with adjacent Ocean County, Monmouth County is a mecca of boating and fishing. Its waterways include several rivers and bays that flow from the Raritan Bayshore into Raritan Bay and Lower New York Bay and into the Atlantic Ocean. The Manasquan Inlet is located in the county, which connects the Atlantic Ocean with the estuary of the Manasquan River, a bay-like body of saltwater that serves as the starting point of the Intracoastal Waterway, which attracts as many as 1,600 boats each weekend during the peak season.

Monmouth County is governed by a five-member Board of Chosen Freeholders, who are elected at-large for three-year terms of office on a staggered basis, with either one or two seats up for election each year. Each January, the freeholders select one of their members to serve as the director of the board for the year to preside over the meetings and activities of the board. Monmouth County’s Freeholders have both administrative and policy making powers. The freeholders oversee the five mandatory functions of county government delegated to it by the state.

Monmouth County is covered by 53 different fire departments, which contain 135 individual fire companies and over 7,000 volunteer firefighters, who are all represented by the Monmouth County Firemen’s Association.
The Monmouth County Fire Marshal’s Office is responsible for training all of the firefighters through the Monmouth County Fire Academy, as well as investigating any fires which may be deemed suspicious and/or involving a fatality. The Monmouth County fire marshal and his staff – including assistant fire marshals and academy staff – are appointed by the County Board of Chosen Freeholders.
With the exception of the fully professional Asbury Park Fire Department and the US Navy Fire Department at NWS Earle, the remainder of the municipalities in the county have volunteer or combination fire departments. The largest volunteer department is in Middletown Township with 11 stations and 350 active members, special services, air and fire police units, in addition to operating its own training facility.
In terms of hazardous material (HazMat) emergencies, very few towns, notably Middletown which has a special services unit, have special units to respond to these types of emergencies. Fort Monmouth responded to most HazMat cases prior to the closing of the base. Naval Weapons Station Earle is also available for HazMat incidents.
Brookdale Community College is the two-year community college for Monmouth County, one of a network of 19 county colleges statewide. The school is located in the Lincroft section of Middletown Township, having been founded in 1967. Rutgers University has a partnership with Brookdale which offers bachelor’s degree completion programs at Brookdale’s Freehold campus.
In addition to multiple public high schools, parochial schools in Monmouth County include St. Rose High School, Red Bank Catholic High School, Christian Brothers Academy, St. John Vianney High School, and Mater Dei High School, which operate under the auspices of the Roman Catholic Diocese of Trenton. A secular private school, Ranney School, is also located in the county.
