Serena Williams has won seven Australian Open singles titles.
Her victories came in 2003, 2005, 2007, 2009, 2010, 2015 and 2017. The run began with a victory over her sister, Venus Williams, in the 2003 final and ended with another all-sisters final in 2017.
Williams’ seven titles are the most by any woman in the Australian Open’s Open Era, which began in 1969. Her 2017 triumph was especially notable because she defeated Venus while pregnant, a fact that became widely known after her subsequent announcement.
A common mix-up is confusing Williams’ seven Australian Open titles with her 23 Grand Slam singles titles overall. Margaret Court holds the tournament’s all-time women’s singles record with 11 championships, including seven from the pre-Open Era. Williams’ total is the Open Era benchmark.
