An English navigator, Henry Hudson, and his crew aboard the Dutch vessel Half Moon, in 1609, 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 in the area were a group of Quaker families from Long Island who 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 the Rhode Island Monmouth Society or 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.

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 here.
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.
Monmouth University is a four-year private university located in West Long Branch that was founded in 1933 as Monmouth Junior College.
Monmouth County utilizes a mutual aid system, in which surrounding municipalities are available to send their resources to incidents where extra help or expertise is needed.
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.
With the exception of the fully paid Asbury Park Fire Department, 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.
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, currently Hank Stryker, and his staff – including assistant fire marshals and academy staff – are appointed by the County Board of Chosen Freeholders.
Monmouth County is covered by 53 different fire districts, which contain 135 individual fire companies and over 7,000 volunteer firefighters, who are all represented by the Monmouth County Firemen's Association.
