Monmouth County is a major residential, economic and coastal centre in Central New Jersey. It includes densely developed suburbs, historic boroughs, Atlantic Ocean resort communities, working farms, corporate campuses and large areas of protected parkland.
Freehold Borough is the county seat and the main centre of county administration and judicial operations. Middletown is the county’s largest municipality by population, while Howell, Marlboro, Manalapan, Freehold Township, Long Branch, Asbury Park and Wall are other important communities.
The county’s position between New York City, northern New Jersey and the Jersey Shore supports a diverse economy. Healthcare, professional services, technology, retail, tourism, education and construction provide substantial employment. Ferries, railway services and major highways also make parts of Monmouth County suitable for commuting to New York City and other regional employment centres.

Location and Geographic Structure
Monmouth County lies along the Atlantic Ocean in east-central New Jersey. Middlesex County is to the north, Mercer County lies to the west, Burlington and Ocean counties are to the south, and the Atlantic Ocean and Raritan Bay form much of its eastern and northeastern boundaries.
Its landscape can be divided into several distinct areas:
- Bayshore communities along Raritan and Sandy Hook bays
- Atlantic Ocean beach towns
- Established northern suburbs
- Central commercial and residential corridors
- Western agricultural communities
- Rural and low-density southern townships
- Historic borough centres
- Preserved parks, reservoirs and natural areas
Important geographic features include Sandy Hook, the Navesink River, Shrewsbury River, Shark River, Manasquan River, Swimming River Reservoir and Manasquan Reservoir.
The county was officially created on March 7, 1683, as one of the original counties formed by the Provincial General Assembly of East Jersey. Its name is generally associated with Monmouthshire in Wales, although another tradition links it with the Duke of Monmouth.
Major highways include the Garden State Parkway, Interstate 195, U.S. Routes 9 and 35, and New Jersey Routes 18, 33, 34, 36, 66, 71, 79 and 138.
Municipalities and Communities
Monmouth County contains 53 incorporated municipalities. Unlike counties in many other states, almost every part of New Jersey is located within an incorporated city, borough, township, town or village. Monmouth County therefore has virtually no conventional unincorporated territory.
Important cities include:
- Asbury Park
- Long Branch
Larger townships include:
- Aberdeen
- Colts Neck
- Freehold
- Hazlet
- Holmdel
- Howell
- Manalapan
- Marlboro

- Highlands
- Keansburg

- Spring Lake
- Tinton Falls
- West Long Branch
Every municipality has its own governing body and is generally responsible for local planning, zoning, building permits, municipal streets, property-code enforcement and local policing arrangements.
Residents should distinguish between municipalities with similar names. Freehold Borough and Freehold Township, for example, are separate governments. Neptune City and Neptune Township are also separate municipalities, as are Shrewsbury Borough and Shrewsbury Township. The county’s official directory identifies all 53 municipal governments.

Housing prices are especially high in communities with railway stations, ferry access, beaches, strong commercial centres or convenient connections to northern New Jersey and New York City. Seasonal properties and tourism demand also influence housing conditions in several coastal municipalities.

County Administration and Government
Monmouth County is governed by a five-member Board of County Commissioners. Commissioners are elected countywide to staggered three-year terms. Each year, the Board selects a director and deputy director from among its members.
The 2026 Board consists of:
- Director: Thomas A. Arnone
- Deputy director: Dominick “Nick” DiRocco
- Commissioner: Susan M. Kiley
- Commissioner: Ross F. Licitra
- Commissioner: Erik Anderson
The Board performs both legislative and executive functions. It adopts the county budget, authorises expenditures and borrowing, approves contracts, supervises county property and appoints officials and members of boards, commissions and authorities.
It is also responsible for funding roads, bridges, parks, libraries, human services, emergency management, the Sheriff’s Office and other regional programmes. The current Board and its 2026 leadership are confirmed by the county’s official commissioner directory.
Municipal councils remain independent. The County Commissioners do not directly manage the daily operations of Monmouth County’s cities, boroughs and townships.
County Administrator and Administrative Leadership
Teri O’Connor serves as Monmouth County administrator. She has held the position since 2010 after previously working as deputy county administrator and director of the Department of Administrative Services.
The county administrator is the highest-ranking appointed administrative official and supervises the daily operations of departments under the Commissioners’ authority.
Major responsibilities include:
- Implementing policies adopted by the Commissioners
- Supervising administrative departments
- Preparing and administering the county budget
- Coordinating public programmes
- Managing departmental performance
- Advising the Board
- Overseeing major projects
- Coordinating with municipalities and state agencies
- Supporting shared-service programmes
The independently elected sheriff, clerk and surrogate do not operate under the administrator in the same manner as ordinary county departments. The prosecutor is appointed under New Jersey law and also exercises independent legal authority.

The Sheriff’s Office manages the county Office of Emergency Management and public-warning operations.
