Amerika Açık Tenis Turnuvası (U.S. Open), Grand Slam`lerin 4`cüsü ve sonuncusudur. Her yıl Ağustos ayının son Pazartesi günü başlar ve iki hafta sürer. Amerika`da New York eyaletinde Queens`te (Flushing Meadows) yapilmaktadir. Turnuva hem bayan hem de erkekleri içermektedir. Yaklaşık 16 milyon dolar toplam ödül dağıtılan turnuvada tekler şampiyonları 1 milyon dolara yakın ödül almaktadırlar.
Turnuva sert zemin üzerinde oynandığından tenisin hızlı oynanmasına olanak vermektedir. Daha önceleri yeşil olan sentetik kortlar 2005 yılında topun daha iyi görünmesi sağlamak üzere mavi kortlarla değiştirilmiştir.
Ana kort, ``Arthur Ashe Stadyumu``, 23 bin koltuk ile dünyanın en büyük tenis stadyumudur.
1990`da tek erkekler şampiyonu olan Pete Sampras en genç erkek şampiyon unvanını eline tutmaktadır. Bayanlarda en genç şampiyon ise 1979`da turnuvayı 16 yaşındayken kazanan Tracy Austin`dir.
