Warren County is a county located in the U.S. state of New Jersey. According to the 2020 census, the county was the state's 19th-most populous county,[8] with a population of 109,632,[5][6] its highest decennial count ever and an increase of 940 (+0.9%) from the 2010 census count of 108,692,[9] which in turn reflected an increase of 6,255 (+6.1%) from 102,437 counted at the 2000 census.[10] The county is part of the North Jersey region of the state.[11][12]

The county borders the Delaware River and Easton, Pennsylvania in the Lehigh Valley to its west, the New York City metropolitan area to its east,[13] the Poconos to its northwest, and Hunterdon County to its south.

Warren County constitutes part of the Allentown-Bethlehem-Easton, PA-NJ metropolitan statistical area in the Lehigh Valley and is the only New Jersey county not a part of the combined statistical areas of either New York City or Philadelphia. The county's most populous municipality is Phillipsburg, with 15,249 residents at the time of the 2020 census[6] while Hardwick Township had both the largest area, 37.92 square miles (98.2 km2), and the fewest people with 1,696 residents.[14] Its county seat is Belvidere.[3]

Warren County was incorporated by an act of the New Jersey Legislature on November 20, 1824, from portions of Sussex County. At its establishment, the county consisted of the townships of Greenwich, Independence, Knowlton, Mansfield, Oxford, and the now defunct Pahaquarry.[1]

Warren County is named for Joseph Warren, a patriot during the American Revolution and Founding Father of the United States who was killed in action by British troops at the Battle of Bunker Hill, in Charlestown, Massachusetts on June 17, 1775.
