is a township in Hudson County, New Jersey, United States. As of the United States 2000 Census, the township had a total population of 58,092.
North Bergen was incorporated as a township on April 10, 1843, by an Act of the New Jersey Legislature, from Bergen Township. Portions of the township have been taken to form Hoboken Township (April 9, 1849, now the City of Hoboken), Hudson Town (April 12, 1852, later part of Hudson City), Hudson City (April 11, 1855, later annexed by Jersey City), Guttenberg (formed within the township on March 9, 1859, and set off as an independent municipality on April 1, 1878), Weehawken (March 15, 1859), Union Township and West Hoboken Township (both created on February 28, 1861), Union Hill town (March 29, 1864) and Secaucus (March 12, 1900).
According to the United States Census Bureau, the township has a total area of 5.6 square miles (14.6 km²), of which, 5.2 square miles (13.5 km²) of it is land and 0.4 square miles (1.1 km²) of it (7.47%) is water. North Bergen meets with Union City and Jersey City at a single point.
Shaped like an inverted "L", North Bergen has a large section stretching from north to south, and a smaller section stretching from east to west. That small north-east portion of North Bergen is considered the Woodcliff section. This area is directly juxtaposed to the Braddock North Hudson Park, along Woodcliff Avenue & JFK Boulevard East. Since this small stretch of land has river exposure to the east, the park to the west, and is sandwiched between the two towns of Cliffside Park (Bergen County) to the north, and Guttenberg (Hudson county) to the south, it is in high demand. This area is considered geographically and demographically separated from the rest of North Bergen.
North Bergen also has a diverse amount of geological features. For example, a rock formation in western North Bergen (located at ) is composed of unusual serpentine rock and made up of small rock cliffs. Because of this, it is unusable by developers, and is one of the few undeveloped parts of North Bergen.
