The 2007 US Open was held from 27 August to 9 September 2007, at USTA Billie Jean King National Tennis Center at Flushing Meadows, New York City.
Roger Federer successfully defended his title, becoming the first man in the open era to win four consecutive US Open titles. Maria Sharapova was unsuccessful in defending her 2006 title, being upset in the third round by 18-year-old Agnieszka Radwańska of Poland. Justine Henin, the runner-up to Sharapova in 2006, won her second US Open title, this year without losing a set. It was the second Grand Slam she won in the year without losing a set, having also won the 2007 French Open earlier in the year. It was also her last grand slam title.
