The US Open, formally the United States Open tennis championships, is a tournament (tennis) is the modern incarnation of one of the oldest tennis championships in the world, with the U.S. National Championship (for mens singles) first contested in 1881. Since 1987, the US Open has been chronologically the fourth and final Grand Slam tennis tournament each year. It is held annually in August and September over a two-week period (the weeks before and after Labor Day weekend). The main tournament consists of five different event championships: mens and womens singles, mens and womens doubles, and mixed doubles, with additional tournaments for senior, junior, and wheelchair players. Since 1978, the tournament has been played on acrylic hard courts at the USTA Billie Jean King National Tennis Center at Flushing Meadows-Corona Park in Queens, New York City.

The US Open differs from the other three Grand Slam tournaments in that there are final-set tiebreaks. In the other three tournaments, the fifth set for men and the third set for women continue until someone wins by two games.
