The Hackensack River is a river, approximately 45 miles (72 km) long, in the U.S. states of New York and New Jersey, emptying into Newark Bay, a back chamber of New York Harbor. The watershed of the river includes part of the suburban area outside New York City just west of the lower Hudson River, which it roughly parallels, separated from it by the New Jersey Palisades. It also flows through and drains the New Jersey Meadowlands. The lower river, which is navigable as far as the city of Hackensack, is heavily industrialized and forms a commercial extension of Newark Bay. Once believed to be among the most polluted water courses in the United States, it staged a modest revival by the late 2000s.

Berry's Creek is a tributary of the Hackensack River in the New Jersey Meadowlands in Bergen County, New Jersey. The creek watershed contains a diverse array of wetlands, marshes, and wildlife. The creek runs through a densely populated region and has been subject to extensive industrial pollution during the 19th and 20th centuries. Several companies discharged toxic chemicals into the creek in the 20th century, and these chemicals have remained in the sediment. The creek has the highest concentrations of methyl mercury of any fresh-water sediment in the world. Portions of the creek watershed are Superfund sites and cleanup projects began in the late 20th century.

The Gateway Program is the planned phased expansion and renovation of the Northeast Corridor (NEC) rail line between Newark, New Jersey and New York City, New York. The right-of-way runs between Newark Penn Station and New York Penn Station (NYP). The project would build new rail bridges in the New Jersey Meadowlands and new tunnels under Bergen Hill and the Hudson River, as well as the conversion of the James Farley Post Office into Moynihan Train Hall and construction of a new terminal annex.

Kearny Generating Station is a peaking power plant on the banks of the Riverbend of the Hackensack River in South Kearny, New Jersey. Owned and operated by Public Service Electric and Gas Company (PSEG) the power station consists of 10 simple cycle combustion turbines totaling 456 MW. It is part of the PJM Interconnection of the Eastern Interconnection grid electric transmission system.

Lake DeForest, also called DeForest Lake, is a reservoir in Clarkstown, New York, created in 1956 by impounding the Hackensack River, which is a principal part of the water supply for Rockland County, New York and Northern New Jersey, mainly Bergen and Hudson counties. The reservoir is owned and operated by Suez North America, and is the most upstream of its reservoirs along the river's watershed, the others being Lake Tappan, the Woodcliff Lake Reservoir, and the Oradell Reservoir. It has a storage capacity of 5.6 billion gallons. Swimming and bathing are disallowed because the water is reserved for potable use. The lake is traversed by a causeway carrying Congers Road.

Lake Tappan is a reservoir impounded by the Tappan Dam on the Hackensack River, straddling the border between the U.S. states of New Jersey and New York. Within New Jersey, the lake traverses the border separating the municipalities of River Vale and Old Tappan in Bergen County, while extending northward across the New York state line into the town of Orangetown in Rockand County. The reservoir was formed in 1967, flooding areas that included the former CAPROC Field Civil Air Patrol airstrip.

USS Ling (SS/AGSS/IXSS-297) is a Balao-class submarine of the United States Navy, named for the ling fish, also known as the cobia. The ship was grounded in the Hackensack River at the former location of the defunct New Jersey Naval Museum in Hackensack, New Jersey. It is now afloat again and an effort is underway to find a new home for the Ling. It is inaccessible to the public.

This is a list of vehicular and rail bridges, tunnels, and cuts in Hudson County, New Jersey. Located in the northeastern part of New Jersey Hudson lies at the heart of the Port of New York and New Jersey and is a major crossroads of the New York Metropolitan area and Northeast Megalopolis. Located on two peninsulas, formerly known as Bergen Neck and New Barbadoes Neck, it has extensive waterfront along the Hudson River, Upper New York Bay, Kill van Kull, Newark Bay and the Hackensack and Passaic Rivers. The main part of Hudson lies on Bergen Hill, the southern emergence of the Hudson Palisades, starting at sea level at Bergen Point and rising to 260 feet travelling through Bayonne, Jersey City and North Hudson. Secaucus and most of West Hudson are part of the New Jersey Meadowlands. Listings are generally from south to north.

New Bridge was a prosperous mill hamlet, centered upon a bridge strategically placed at the narrows of the Hackensack River. In the American Revolution, New Bridge Landing was the site of a strategic bridge crossing the Hackensack River, where General George Washington led his troops in retreat from British forces November 20, 1776. Eleven engagements took place here throughout the war. The current Draw Bridge at New Bridge was installed in 1889 and added to the National Register of Historic Places on July 5, 1989. The area is now a New Jersey historic site in portions of New Milford, River Edge, Hackensack and Teaneck in Bergen County, New Jersey, United States.

The New Jersey Naval Museum (NJNM) was a museum located along the Hackensack River in Hackensack in Bergen County, New Jersey, United States. Its mission was dedicated to the state's Navy heritage and naval history in general. The prominent element in the collection was the USS Ling (SS-297), a 312-foot (95 m) long Balao-class submarine of World War II. The museum land has since been sold for redevelopment, however the USS Ling remains grounded in the river, with an uncertain future. Efforts have been made since 2007 to find a new home for the Ling. In 2019, the Louisville Naval Museum began a campaign to attempt to relocate the ship to the Ohio River.

The New Milford Plant of the Hackensack Water Company was a water treatment and pumping plant located on Van Buskirk Island, an artificially created island in the Hackensack River, in Oradell, Bergen County, New Jersey, United States. The site was purchased in 1881 by the Hackensack Water Company, which developed it for water supply use. The facility was built between 1881 and 1911, and it includes a brick pumping station from 1882, a tall filtration tower, and huge underground infrastructure. The Hackensack Water Company was merged into United Water in the 1980s; the successor today is Suez North America.

The Oradell Reservoir is a reservoir formed by the Oradell Reservoir Dam on the Hackensack River in Bergen County, New Jersey, USA.
