2026 Australian Open – Women's singles

Elena Rybakina defeated Aryna Sabalenka in the final, 6–4, 4–6, 6–4 to win the women's singles tennis title at the 2026 Australian Open. It was her second major title. Rybakina was the fourth woman (after Jennifer Capriati, Serena Williams, and Madison Keys) since the establishment of the WTA rankings to defeat both the world No. 1 and No. 2 players en route to the Australian Open title, and the second consecutive year to do so. The final was a rematch of the 2023 final, won by Sabalenka.

Keys was the defending champion, but lost in the fourth round to Jessica Pegula.

Sabalenka was the first woman to reach four consecutive Australian Open women's singles finals since Martina Hingis in 2000. Sabalenka and Rybakina both reached the final without losing a set en route, the first time both finalists at a major did so since Serena and Venus Williams at the 2008 Wimbledon Championships.

Aged 45 years and 7 months old, Venus Williams became the oldest woman to compete in the singles main draw at the Australian Open, surpassing the previous record set by Kimiko Date in 2015. The first round match between Karolína Plíšková and Sloane Stephens was the first major main draw match contested between two players ranked outside the top 1,000 since the current WTA Tour format was established in 1990.

Zeynep Sönmez became the first Turkish woman to record a win at the event and the first Turkish player to advance to the third round. This was the first Australian Open to have four Americans in the quarterfinals since 2001. For the first time in the Open Era, the top six seeds reached the quarterfinals in both the women's and men's singles competitions.
