Queens is the largest in area, the second-largest in population, and the easternmost of the Five Boroughs which form the City of New York. The Borough of Queens' boundaries are identical to those of the County of Queens (Queens County), a subdivision of the State of New York in the Northeastern United States.

Located on the western portion of Long Island, Queens is home to two of the three major New York City area airports, John F. Kennedy and LaGuardia; it is also the location of the New York Mets baseball team; the US Open tennis tournament; Flushing Meadows Park and Silvercup Studios.

As of the 2005[update] American Community Survey, immigrants comprise 47.6% of Queens residents.[1] With a population of 2.3 million it is the second most populous borough in New York City (behind Brooklyn) and the tenth most populous county in the United States. It is also the nation's fourth-most-densely populated county (after the counties covering Manhattan, Brooklyn and the Bronx).[2] The 2.3 million figure is the highest historical population for the borough.[3] Were each borough an independent city, Queens would be the fourth largest city in the United States.
