Teterboro (/ˈtiːtərbəroʊ/ TEE-tər-bər-oh) is a borough in Bergen County, in the U.S. state of New Jersey. As of the 2020 United States census, the borough's population was 61, a decrease of 6 (−9.0%) from the 2010 census count of 67, which in turn reflected an increase of 49 (+272.2%) from the 18 counted in the 2000 census. After being ranked as the fourth-smallest municipality, by population, in New Jersey through the 2010 census, the borough is the third-smallest since the merger of Pine Valley into Pine Hill in 2022.
 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 borough's ratables (the value of land and buildings which are assessed for property taxes). Some have argued that the population is too small for the borough to justify its own existence. However, all such attempts have met with failure. 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 borough officials, residents, business and land owners, and the neighboring municipalities of Moonachie and Hasbrouck Heights. Legislators attempted to include a 20-year tax abatement within the bill to alleviate the concerns of Teterboro business and property owners who were concerned that taxes could spike if the borough was dissolved. The legality of such an abatement was also called into question.
 According to the United States Census Bureau, the borough had a total area of 1.11 square miles (2.88 km2), including 1.11 square miles (2.87 km2) of land and <0.01 square miles (0.01 km2) of water (0.36%).
 The borough borders the Bergen County municipalities of Hackensack, Hasbrouck Heights, Little Ferry, Moonachie and South Hackensack.

 Borough officials stated that the 2000 census had failed to count any of the residents of the Vincent Place housing units who had moved into the newly built homes in 1999. The uncounted residents, including the Mayor and all four council members, would help account for a projected tripling of the population enumerated by the census. Previously, the Mayor and Council, as well as several other Vincent Place residents, had all been residents of Huyler Street, the only other street zoned as a residential area in the borough. In a March 2010 article, published in The Record, Teterboro's municipal manager at the time noted that the actual population of the town had grown to approximately 60.
 Teterboro is governed under the 1923 Municipal Manager Law form of New Jersey municipal government. The borough is one of seven municipalities (of the 564) statewide that use this form of government. The governing body is comprised of a five-member Borough Council, with all positions elected at-large on a non-partisan basis to four-year terms on a concurrent basis in elections held as part of the November general election. At a reorganization meeting held in July after each election, the Council members provide nominations from within itself before electing one of its members to serve as mayor.
 As of 2023, Teterboro's Borough Council consists of Mayor John P. Watt, Christie Emden, Juan Ramirez, Gregory Stein and John B. Watt, all serving concurrent terms of office ending December 31, 2026.
