The US Open started as an event for amateur originally called the US National Championships in Newport, Rhode Island at the Newport Casino. In its first year in 1881, only men were competing for a championship title until 1887 when women also participated for women's singles and the doubles titles began in 1889.

In 1892, the U.S. Mixed Doubles Championship formally became part of the tournament. The venue for the US Open stayed in Rhode Island for 34 years. In 1915, the tennis tournament became too big for its location on Rhode Island and changed its venue to the West Side Tennis Club in Forest Hills, New York until 1977.

The West Side Tennis Club featured grass courts until 1975 when the court surfaces were changed to green clay courts or Har-Tru surface. In 1978, the venue changed again to its current location in Flushing Meadows, NY with the current acrylic hard court surfaces. It is at the USTA Billie Jean King National Tennis Center in Corona Park in the Queens borough of New York City.

The U.S Open is the fourth and final Grand Slam in professional tennis running from late August for two weeks into September. Currently, $18.5 million is offered by the US Open to over 600 men and women.
