Passaic County, New Jersey is a populous and historically significant county located in the northern part of the state. It is anchored by the city of Paterson, a major hub of early American industrialization known as the "Silk City." The county features a diverse landscape ranging from the urban core of the New York metropolitan area to the protected woodlands of the New Jersey Highlands and portions of the Delaware Water Gap National Recreation Area.
The area was originally inhabited by the Lenape people before European settlement began in the 17th century under the Dutch and later English colonial rule. The county was created by an act of the New Jersey Legislature on February 7, 1837, from portions of Bergen and Essex counties. Its development was profoundly shaped by Alexander Hamilton and the Society for the Establishment of Useful Manufactures, which founded Paterson in 1791 to harness the power of the Great Falls of the Passaic River. This initiative spurred the growth of major industries, including Colt firearms, locomotive manufacturing by the Rogers Locomotive and Machine Works, and the dominant silk trade, attracting waves of immigrants from Italy, Syria, and Eastern Europe. The 1913 Paterson silk strike was a pivotal event in the American labor movement.
According to the U.S. Census Bureau, the county has a total area of 197.33 square miles, of which 184.66 square miles is land and 12.67 square miles is water. It is bordered by Bergen County to the east, Essex County and Morris County to the south, and Sussex County to the west, with a short border along the New York state line to the north at Suffern. Major waterways include the Passaic River, which flows through Paterson and the Great Swamp National Wildlife Refuge, and the Wanaque River. Notable natural features include the Ramapo Mountains, Apshawa Preserve, and Ringwood State Park.
As of the 2020 United States census, the population was 524,118, making it the seventh-most populous county in New Jersey. The racial and ethnic composition is diverse, with significant Hispanic or Latino communities, particularly of Dominican and Peruvian descent, alongside large Italian-American, Arab-American, and Asian-American populations. Major population centers include Paterson, Clifton, Wayne, and Passaic. The county is part of the New York metropolitan area and has been a primary destination for new immigrants for over a century.
Passaic County operates under a Board of County Commissioners form of government. The county is part of the 5th, 8th, 9th, and 11th congressional districts. The county seat is the historic Paterson City Hall in Paterson. Other key offices include the Passaic County Sheriff's Office and the Passaic County Prosecutor's Office. The county falls under the jurisdiction of the New Jersey Superior Court.
