Moonachie is a borough in Bergen County, New Jersey, in the Hackensack River watershed. As of the 2010 United States Census, the borough's population was 2,708, reflecting a decline of 46 (-1.7%) from the 2,754 counted in the 2000 Census, which had in turn declined by 63 (-2.2%) from the 2,817 counted in the 1990 Census.
Moonachie was incorporated as a borough by an Act of the New Jersey Legislature on April 11, 1910, from portions of Lodi Township, based on the results of a referendum held on May 3, 1910. On March 26, 1917, portions of Moonachie were taken to form Teterboro. Legend is that Moonachie was named after Chief Monaghie, a member of the Iroquois who inhabited the local cedar forests.
The name of the borough is typically pronounced "moo-NAH-kee;" however, in January 1987, then-Mayor of New York City Ed Koch pronounced it "mah-NOO-chee" when he made his now-famous quip that the New York Giants should hold their victory parade in the borough after the team had just won Super Bowl XXI. Koch had refused to grant the Giants permission to hold a parade within the city limits because the team plays its home games in New Jersey, not in New York City.
