2007 US Open – Women's singles
Justine Henin defeated Svetlana Kuznetsova in the final, 6–1, 6–3 to win the women's singles tennis title at the 2007 US Open. She did not lose a set during the tournament. It would be her last major title, as well as her final US Open appearance. Maria Sharapova was the defending champion, but was defeated by Agnieszka Radwańska in the third round. This was the final appearance of former world No. 1 and five-time Grand Slam singles champion Martina Hingis in a Grand Slam singles tournament, who retired in November 2007 (she  would later return to Grand Slam competition in doubles and mixed doubles in 2013, retiring for good at the end of the 2017 season). She was beaten in the third round by Victoria Azarenka. It was also the first US Open main draw appearance for future world No. 1 and two-time US Open finalist Caroline Wozniacki, who lost in the second round to Alizé Cornet.
