Harrington Park is a borough in Bergen County, New Jersey, in the Northern Valley region near the Hackensack River. With a population of about 4,700, it is a small, predominantly residential community of single-family homes set on tree-lined streets, known for its quiet atmosphere and strong schools. The borough's character is suburban and family-oriented. Most of its housing consists of well-kept single-family homes on modest to generous lots, and the community has little commercial development, relying on neighboring towns such as Closter, Old Tappan, and Westwood for shopping and services. Its residents are drawn by the combination of a peaceful, safe setting and convenient access to New York City. Education is a defining feature. The Harrington Park School District operates the community's pre-kindergarten through eighth-grade programs at its local school, after which students attend Northern Valley Regional High School at Old Tappan, part of one of the state's recognized regional districts. The school system is a central reason families settle in the borough. Recreation and open space are close at hand. The borough sits near the Oradell Reservoir and the Hackensack River corridor, and its neighborhoods include local parks and playgrounds. The broader Northern Valley offers additional parks, trails, and the retail and dining along the county's northern corridor. For commuters, NJ Transit buses and Rockland Coaches provide service toward New York, and the Pascack Valley Line rail runs nearby, keeping Manhattan within a reasonable commute. Harrington Park's blend of strong schools, established neighborhoods, and metro access makes it a sought-after address in Bergen County's Northern Valley.
