The 2012 Australian Open was a tennis tournament that took place in Melbourne Park in Melbourne, Australia, from 16 to 29 January 2012. It was the 100th edition of the Australian Open, and the first Grand Slam event of the year. The tournament consisted of events for professional players in singles, doubles and mixed doubles play. Junior and wheelchair players competed in singles and doubles tournaments.

Novak Djokovic successfully defended his title after he defeated Rafael Nadal in the longest grand slam final in history. The 2012 final passed the 2008 Wimbledon final for the record, finishing after 5 hours and 53 minutes of play. Kim Clijsters was the defending champion for the women's singles, but lost to Victoria Azarenka in the semifinals. Azarenka defeated Maria Sharapova for her first Grand Slam title; and over took Caroline Wozniacki as the number one ranked player on the WTA Tour. In the doubles Leander Paes and Radek Štěpánek won the title. Paes completed a career Grand Slam with the title while Štěpánek won his first Slam. On the women's side an all Russian duo of Svetlana Kuznetsova and Vera Zvonareva took the title. The mixed event was won by Bethanie Mattek-Sands and Horia Tecău.
