2009 Us Open – Women's Singles

It was her second US Open title and her second major singles title overall. She became the first unseeded player and wild card to win the title, and the first mother to win a major since Evonne Goolagong in 1980. Following her win, she appeared at 19th in the rankings. This was the first time since the 2007 Australian Open where Clijsters participated in a major, as she was contesting just her third tournament since coming out of retirement.

Serena Williams was the defending champion, but was defeated in the semifinals by Clijsters. A foot fault was called for Williams at the end of the second set, producing two match points for Clijsters. Williams argued the call and was given a point penalty for intimidating a line judge, ending the match (having already had a warning for racquet abuse earlier in the match).

Svetlana Kuznetsova's loss in the fourth round guaranteed a first time major finalist from the top half of the draw. Wozniacki became the first Danish woman to reach a major final, and the first Scandinavian to reach the final since Molla Bjurstedt Mallory in 1918.

This was the final major appearance for two-time major champion Amélie Mauresmo, who lost to Aleksandra Wozniak in the second round. This was also the final major singles appearance of Ai Sugiyama, who was on a record-breaking 62nd consecutive major singles appearance, losing in the first round to Samantha Stosur. Sugiyama's record was eventually broken by Alizé Cornet in 2022.
