Hazlet began as Raritan Township, created by the state legislature on February 25, 1848, when the settlements of Hazlet, North Centerville, West Keansburg and several other hamlets were split off from Middletown. Over the following decades the township itself gave up land to form Holmdel and Matawan (now Aberdeen) in 1857, Keyport in 1870, Keansburg in 1917 and Union Beach in 1925. Through the 1800s this was farm country, and growers carted their crops by wagon to steamboat landings on Raritan Bay.
The New York and Long Branch Railroad opened a station on Holmdel Road in 1875. First called Holmdel, the stop was renamed Hazlet in 1879, honoring John Hazlett, a property owner whose estate stood near the old Keyport-Holmdel Turnpike. The railroad let local farms ship asparagus, peaches, peppers and canned tomatoes to city markets. In the 1930s the National Fireproofing Company dug clay beds for fire bricks; the abandoned pits filled with a mix of spring water and salt water and became Natco Lake beside Route 36.
The township grew quickly in the 1960s, adding neighborhood schools, a municipal pool complex and shopping centers. Because several New Jersey municipalities shared the Raritan name, voters chose in a November 1967 referendum to adopt the name of the train stop, and the change to Hazlet Township took effect later that month. Route 35 was also home to New Jersey's last drive-in movie theater, which closed in 1991. The township marked its 175th anniversary in 2023.
Hazlet is a compact, mostly built-out township on the Raritan Bayshore, bordered by Aberdeen, Holmdel, Keyport, Keansburg, Middletown and Union Beach. Roughly three-quarters of its land is developed, nearly all of it residential neighborhoods, with wetlands along its creeks making up most of the rest. The township's population surged in the 1960s, and the neighborhood schools, municipal pool complex and shopping centers built during that boom still shape much of the town.
The township has no traditional downtown. Its retail and commercial life runs along Route 35 and Route 36, the two state highways that cross it, while the train station area sits between Holmdel Road and Hazlet Avenue. Named sections still used locally include North Centerville, Centerville, Mechanicsville, South Keyport, West Keansburg, Tiltons Corner and Van Marters Corner. New construction is limited by the lack of open land; the largest recent project is Grenada Estates, a 312-unit garden-home development being built to state and township flood standards.
Several creeks drain the township toward the bay, including East, Flat, Lappatatong, Thrones and Waackaack creeks, and the mapped flood areas follow them. In West Keansburg, the 3.75-acre 8th Street Park, which lies entirely in a flood zone, was rebuilt starting in 2023 with an inclusive playground, courts and a perimeter walking path. Veterans Park, the township's largest park at about 88 acres, holds the municipal building, a community center and the swim and tennis club. Public schools are run by Hazlet Township Public Schools.
Hazlet station, on NJ Transit's North Jersey Coast Line, sits between Holmdel Road and Hazlet Avenue and has three parking lots with about 600 daily and permit spaces. Trains run north through Aberdeen-Matawan, Perth Amboy, Rahway and Newark to New York Penn Station, with connections at Newark Penn and a stop at the Newark Liberty International Airport station; southbound trains continue toward Red Bank and Long Branch, where riders bound for Asbury Park and Bay Head change to diesel shuttle trains. The station dates to 1875 and was rebuilt in 2003.
By car, the Garden State Parkway's Interchange 117 serves Keyport and Hazlet, and Route 35, Route 36 and County Route 516 are the main roads through town. NJ Transit local bus route 817 serves the township, and private commuter buses to New York City have used a stop on Route 36.
The northern section of the Monmouth County Henry Hudson Trail, a paved former railroad corridor, begins at the Aberdeen-Keyport border just to the northwest and runs about 12 miles east along the Bayshore toward Atlantic Highlands.
Veterans Park is the center of township recreation, with the community center, municipal pool and tennis complex run as the Hazlet Swim and Tennis Club, and the municipal building on its grounds. Natco Lake, the flooded clay pit beside Route 36, has become a natural refuge, and the township has been renovating the surrounding Natco Park. In West Keansburg, 8th Street Park was rebuilt beginning in 2023 with an inclusive playground, an all-purpose court, a basketball court and a walking path.
The Hazlet branch of the Monmouth County Library is at 251 Middle Road, offering public computers, wireless access, scanning and printing. Township traditions include Fourth of July celebrations and Hazlet Day, and the James J. Cullen Center has hosted history talks, including a series during the 2023 anniversary year.
For longer walks and rides, the county's paved Henry Hudson Trail starts nearby at the Aberdeen-Keyport line and follows a former rail corridor east along the Bayshore, with an activity center in the Leonardo section of Middletown.
