Which city hosts the US Open tennis tournament?

New York City hosts the US Open tennis tournament.

The tournament is played at the USTA Billie Jean King National Tennis Center in Flushing Meadows–Corona Park, in the Queens borough of New York City. The complex has been the US Open's home since 1978, when the event moved from the West Side Tennis Club in Forest Hills, Queens.

The venue includes Arthur Ashe Stadium, Louis Armstrong Stadium, and the Grandstand. Arthur Ashe Stadium, named for the American champion and civil-rights advocate, is the tournament's main court and has one of the largest capacities in tennis.

A common mix-up is to answer “Queens” or “Flushing Meadows.” Those names identify the borough and park where the grounds are located, while New York City is the city requested by the question. The tournament itself is held in New York, even though its official name refers to the United States.
