Monmouth County is a county in New Jersey, United States, on the Jersey Shore about 30 miles south of Newark. It had a population of 643,615 at the 2020 census, an estimated 651,035 by 2025, and covers 661.40 square miles (1,713.0 km2) centred near 40°17′N 74°09′W.<\/p>\n
Freehold Borough is the county seat; its postal code is 07728. The county holds 2 cities, 1 village, 35 boroughs and 15 townships — 53 municipalities in all, since New Jersey has no unincorporated land — and it runs on Eastern Time. Its FIPS code is 34025.<\/p>\n
Monmouth County has 53 municipalities on record, more than any other county covered on this site: 2 cities (Asbury Park and Long Branch), 1 village (Loch Arbour), 35 boroughs and 15 townships. Every square mile of the county belongs to one municipality or another — New Jersey abolished unincorporated land more than a century ago — so “Township” and “Borough” below are full municipal governments, not subdivisions of a larger town.<\/p>\n

Neptune City is its own borough, entirely separate from the larger Neptune Township that surrounds it on three sides — both use the Neptune post office but keep separate governments. Shrewsbury Borough and Shrewsbury Township are also two different municipalities: the borough sits west of Red Bank, while the township is a small pocket a few miles south, wholly surrounded by Tinton Falls and Eatontown.<\/p>\n ZIP Codes<\/h2>\nTwelve boroughs and townships have no ZIP code of their own on record — Interlaken, Lake Como, Loch Arbour, Manalapan, Neptune City, Sea Bright, Shrewsbury Township, Spring Lake Heights, Tinton Falls, Union Beach, Upper Freehold (outside the Allentown and Cream Ridge zones) and Wall — and mail there is sorted under a neighboring town’s code rather than a code unique to the municipality.<\/p>\n Geography<\/h2>\nMonmouth County sits at the northern end of the Jersey Shore, where sandy barrier beaches along the Atlantic give way to a rolling Piedmont interior. Of its 661.40 square miles, 468.18 are land and 193.22 are water — 29.2 percent of the county, the highest share of any inland New Jersey county, reflecting its long Atlantic coastline plus the tidal marshes and inlets of the Raritan Bayshore in the north. Howell Township, at 61.21 square miles, is the largest municipality by area; Middletown Township, with 67,106 residents, is the most populous. Sandy Hook, a barrier spit in Middletown Township, carries the 1764 Sandy Hook Light, the oldest operating lighthouse in the United States, and is part of Gateway National Recreation Area.<\/p>\n Middlesex County borders Monmouth to the northwest, Mercer County to the west, Burlington County to the southwest, and Ocean County to the south. Middlesex County<\/a>, Mercer County<\/a>, Burlington County<\/a> and Ocean County<\/a> all border Monmouth directly; across the Raritan Bay to the north lie New York City’s Staten Island, Brooklyn and Queens, with no land connection.<\/p>\n Monmouth County had a population of 643,615 at the 2020 census, and the latest estimate puts the county near 651,035 residents by 2025. Middletown Township and Howell Township are the two largest communities, together holding roughly a fifth of the county’s population. Median household income runs $102,870, notably higher than New Jersey’s statewide figure of $99,781. Population density works out to about 1,374.7 people per square mile of land, among the denser counties on the Jersey Shore, reflecting Monmouth’s position within the New York metropolitan area.<\/p>\n Monmouth County’s economy produced a gross domestic product of $34.2 billion in 2021, ninth-highest among New Jersey’s 21 counties. Per capita personal income of $69,410 ranked fifth in the state as of 2015. Nokia Bell Labs runs a research campus in Holmdel, in the same building that now also houses Bell Works, a large mixed-use office and retail redevelopment of the original Bell Laboratories site. Naval Weapons Station Earle, commissioned in 1943, occupies more than 11,000 acres reaching into Colts Neck, Tinton Falls and several neighboring townships, and remains a working U.S. Navy ordnance facility. The former Fort Monmouth Army post, which closed under base realignment in 2011, spans Eatontown, Oceanport and Tinton Falls and is being redeveloped for civilian use. Monmouth Medical Center in Long Branch anchors the county’s health care sector, and Brookdale Community College in Middletown Township and Monmouth University in West Long Branch are the county’s two largest institutions of higher education. The county’s biggest annual event is the Haskell Invitational Stakes each July at Monmouth Park Racetrack in Oceanport, a thoroughbred race that has run since the track opened in 1870.<\/p>\n New Jersey’s colonial legislature established Monmouth County on March 7, 1683, as one of the colony’s original four counties alongside Bergen, Essex and Middlesex. It takes its name from Monmouthshire, a county in Wales. Freehold Borough became the county seat and has held that role since.<\/p>\n The Battle of Monmouth was fought in June 1778 during the American Revolutionary War, on ground now preserved as Monmouth Battlefield State Park in Freehold Township and Manalapan Township. Fort Monmouth traces to 1917, when the Army opened Camp Little Silver as a training ground; it grew into a major signal-corps research post before closing in 2011. Sandy Hook Light, built in 1764 on the Sandy Hook peninsula, guided ships into New York Harbor through the Revolutionary War and remains in service today.<\/p>\n The Garden State Parkway runs the length of the county north to south. U.S. Route 9 and New Jersey Routes 18, 34, 35 and 36 cross the county, and Interstate 195 reaches its western edge near Freehold; no other interstate passes through Monmouth.<\/p>\n Newark Liberty International Airport, roughly 30 miles north of Freehold, is the nearest major commercial airport. Monmouth Executive Airport in Wall Township handles general aviation. NJ Transit’s North Jersey Coast Line stops at Red Bank, Little Silver, Long Branch, Matawan and several other county stations on its way to New York Penn Station; the nearest Amtrak station is Metropark, about 22 miles north in Middlesex County. Seastreak ferries also run from Atlantic Highlands and Highlands to Manhattan.<\/p>\n Where is Monmouth County located?<\/strong> What is the population of Monmouth County?<\/strong> How big is Monmouth County?<\/strong> What is the county seat of Monmouth County?<\/strong> How many towns and cities are in Monmouth County?<\/strong> What ZIP codes does Monmouth County use?<\/strong> |
