2023 Australian Open – Women's singles

Aryna Sabalenka defeated Elena Rybakina in the final, 4–6, 6–3, 6–4 to win the women's singles tennis title at the 2023 Australian Open. It was her first major singles title. Sabalenka dropped just one set during the tournament, to Rybakina in the championship match. Rybakina became the first Kazakhstani player to progress past the fourth round, and the first player since Jennifer Capriati in 2001 to defeat three consecutive major champions in a single edition of the Australian Open. By reaching the final, Rybakina made her debut in the top ten of the WTA rankings making her the first player representing Kazakhstan, male or female, ever to reach this milestone.

Ashleigh Barty was the reigning champion, but she retired from professional tennis in March 2022. Barty's retirement and Angelique Kerber and Naomi Osaka’s absences (both due to pregnancy) meant that Victoria Azarenka and Sofia Kenin were the only former champions left in the draw. They met in the first round, with Azarenka winning in straight sets.

Jeļena Ostapenko became the first Latvian to reach the Australian Open quarterfinals.

This tournament marked the final professional major appearance of former world No. 1 and two-time Grand Slam champion Garbiñe Muguruza. She lost in the first round to Elise Mertens. Muguruza later announced her retirement from professional tennis the following year.
