Teterboro ( TEE-tər-bər-oh) is a borough in Bergen County, in the U.S. state of New Jersey. As of the 2010 United States Census, the borough's population was 67, reflecting an increase of 49 (+272.2%) from the 18 counted in the 2000 Census, which had in turn declined by 4 (−18.2%) from the 22 counted in the 1990 Census. As of 2010, it is the fourth-smallest municipality, by population, in New Jersey.
Teterboro is the home of Teterboro Airport (operated by the Port Authority of New York and New Jersey) which takes up a majority of the borough, as well as portions of Hasbrouck Heights and Moonachie.
Teterboro was incorporated on March 26, 1917, from land that was originally part of the boroughs of Moonachie, Little Ferry and Lodi Township. The borough was enlarged on July 5, 1918, by the addition of an area annexed from Hasbrouck Heights. The borough was named for Walter C. Teter, a New York investment banker, who had purchased land in 1917 to build a racetrack and developed a 700-acre (280 ha) site, reclaiming marshland and building an airport and an 18-hole golf course. The name Teterboro was changed on April 14, 1937, to Bendix Borough, but reverted to Teterboro Borough on June 1, 1943.
Throughout the borough's history, neighboring municipalities, such as Hasbrouck Heights and South Hackensack, have made repeated attempts to dissolve Teterboro, in hopes of absorbing the town's ratables. Some have reasoned that the population is too small for the borough to justify its own existence. However, all such attempts have met with failure, due to resistance from residents, business owners and municipal officials. In July 2010, a bill was introduced in the New Jersey state senate in a renewed effort to divide Teterboro among neighboring towns. The bill, sponsored by Senator Robert M. Gordon and Assemblypersons Connie Wagner and Vincent Prieto, stalled in the state Legislature after its introduction, due to opposition from the borough's officials, its residents and business and land owners within the borough, as well as the neighboring municipalities of Moonachie and Hasbrouck Heights.
