The US Open is the Grand Slam tennis tournament traditionally played in New York around the U.S. Labor Day holiday.
The tournament is held at the USTA Billie Jean King National Tennis Center in Flushing Meadows–Corona Park, Queens. Its schedule usually spans the final week of August and the first half of September, placing many major matches and the finals close to Labor Day weekend.
The US Open is the fourth and final Grand Slam tournament of the annual tennis calendar. The other three are the Australian Open, the French Open, and Wimbledon. Unlike the US Open, those tournaments are held in Melbourne, Paris, and London respectively.
The event began as the U.S. National Championships in 1881. It became the US Open in 1968, when the tournament entered the Open Era and admitted both professional and amateur competitors. Labor Day weekend is therefore a familiar part of the tournament’s modern American sporting context.
