Women’s tennis records are spread across different eras, so the numbers need a little context. Margaret Court owns the all-time women’s singles record for Grand Slam titles, while Serena Williams holds the Open Era record. Steffi Graf leads the rankings for weeks at world No. 1, and Martina Navratilova holds a remarkable winning-streak mark.
Here’s a guide to the best-known records in women’s tennis, with a focus on what each achievement means—and why some comparisons between players from different generations are not quite like for like.

Grand Slam singles records
Margaret Court: 24 major titles
Margaret Court won 24 Grand Slam singles titles, the highest total in women’s tennis. Her titles came across all four majors, including a record 11 Australian Championships or Australian Opens. That home-court record is especially striking: Court won the tournament across several stages of her career, as the event and the sport changed around her.
Thirteen of Court’s major titles came before the Open Era began in 1968, when professionals were admitted to the sport’s biggest events. That matters when comparing her total with later players. It doesn’t take away from the record, but it explains why Serena Williams’ 23 titles are often described as the Open Era benchmark.
Serena Williams: 23 Open Era titles
Williams’ 23 major singles titles are the most won by any woman in the Open Era. She won her first at the 1999 US Open and her last at the 2017 Australian Open, beating her sister Venus in the final while pregnant. Her seven Wimbledon singles titles also show how well her powerful serve and aggressive returning worked on grass—not just on the hard courts where she claimed many of her biggest wins.
Steffi Graf sits just behind Williams in the Open Era major-title count, with 22. Graf also owns a unique milestone: in 1988 she won all four majors and Olympic singles gold in the same year, a feat known as the Golden Slam.
Rankings and tour-title records
Graf spent 377 weeks at world No. 1, the most in women’s tennis. The WTA rankings began in 1975, so this record can only be compared among players from the ranking era. Graf’s long stay at the top reflected more than a run of big wins: she remained a threat on every surface, with quick footwork and a powerful forehand that could take control of a point from deep behind the baseline.
Navratilova holds the career record for WTA singles titles, with 167. Her serve-and-volley style was a sharp contrast to Graf’s baseline game, and her success extended well beyond singles. Along with Pam Shriver, she became one of the defining doubles players of her era.
Graf also shares the record for the longest uninterrupted stretch at No. 1: 186 consecutive weeks. Serena Williams reached the same mark during her own time at the top. These records underline the difference between reaching No. 1 and staying there through season after season of challenges.
Winning streaks and consecutive majors
Navratilova won 74 consecutive matches in 1984, the longest winning streak in WTA history. A streak that long demands more than a hot start: players must handle changing opponents, surfaces, travel, and the pressure of knowing every match could end the run. Navratilova’s streak ended at the Australian Open, where Helena Suková beat her in the semifinals.
Navratilova also won six consecutive Grand Slam singles titles, from Wimbledon in 1983 through the US Open in 1984. She did not win six majors in one calendar year; the run crossed seasons. That distinction helps separate a consecutive-title record from a calendar-year Grand Slam, which requires winning the Australian Open, French Open, Wimbledon, and US Open in the same year.
Other notable women’s tennis records
- Youngest Open Era major singles champion: Martina Hingis won the 1997 Australian Open at 16 years old. Her early success also made her the youngest player to reach No. 1 in the WTA rankings.
- Oldest Open Era major singles champion: Serena Williams won the 2017 Australian Open at 35, becoming the oldest woman to claim a major singles title in the Open Era.
- Women’s doubles partnership: Serena and Venus Williams won 14 Grand Slam women’s doubles titles together and did not lose a major final as a team.
- Calendar-year Grand Slam winners: Maureen Connolly, Margaret Court, and Steffi Graf each won all four major singles titles in one year. Graf’s 1988 season also included Olympic gold.
Records tell part of the story, but playing conditions and opportunities have changed over time. Court competed in a different era from Williams, while rankings cannot include champions from before the WTA system began. The fairest comparisons state clearly whether they cover all eras, the Open Era, or the ranking era.
