The US Open's current venue is in Queens, one of New York City's five boroughs.
The tournament is played at the USTA Billie Jean King National Tennis Center in Flushing Meadows–Corona Park, in the Queens neighborhood of Flushing. The complex has hosted the US Open since 1978, when the championship moved from the West Side Tennis Club in Forest Hills, also in Queens. That move brought the event to a larger modern site and coincided with its shift to hard courts.
The borough connection can be confusing because the tournament is often described simply as being in New York City, while the venue's neighborhood and borough are more specific. Queens is geographically east of Manhattan and is one of the city's four outer boroughs, alongside Brooklyn, the Bronx, and Staten Island. Manhattan is the city's central borough, but it has never contained the current US Open grounds.
The site is named for Billie Jean King, a champion, equality advocate, and leading figure in tennis history. Its principal stadiums include Arthur Ashe Stadium, Louis Armstrong Stadium, and the Grandstand. The tournament itself has had several New York-area homes: it moved to Forest Hills in 1915, briefly relocated to Philadelphia from 1921 to 1923, returned to Forest Hills, and then settled in Flushing Meadows in 1978.
