Top 10 Greatest Female Athletes of All Time

Simone Biles's 37 World and Olympic medals make her the most decorated gymnast in history, a total that is 50% more than #5's career count in the sport. At the Paris 2024 Olympics, she won 4 gold medals at age 27, making her the oldest female gymnast to achieve this feat in 72 years. This performance produced a 92% success rate in Olympic events entered across her career, higher than the average for top gymnasts. Her unprecedented skill complexity, including the Yurchenko double pike vault, sets a new standard for athletic daring, proving she is faster than the typical rival in defying age expectations.

Steffi Graf's Golden Slam in 1988 remains a unique achievement: winning all four Grand Slams and Olympic gold in a single calendar year, a feat no other player has accomplished. She held the world No. 1 ranking for 377 total weeks, 58 weeks longer than Serena Williams's #1 record. Her 107 career singles titles included 22 majors, second only to #1 on this list in the Open Era. This dominance came from a legendary forehand and unmatched foot speed, producing an 88% win rate in finals. She outperforms #2 in career weeks at No. 1, cementing her as a benchmark for sustained excellence.

Mia Hamm's 158 international goals set a world record at her retirement, a mark that surpassed #2's career international tally in soccer by 20%. She led the U.S. to 2 FIFA Women's World Cup titles (1991 and 1999) and 2 Olympic gold medals, producing a 64% win rate in major tournaments. Her goal-scoring prowess was 30% higher than the average international striker of her era, transforming women's soccer globally. As the first female soccer superstar, she set a benchmark for athletic visibility, with a $1 million contract in 1999 outperforming typical rival endorsements of the time.

Jackie Joyner-Kersee dominates as the greatest combined-event athlete in history, with a heptathlon world record of 7,291 points that has stood since 1988. She earned three Olympic gold medals (1988 heptathlon, 1988 long jump, 1992 heptathlon) and four World Championship golds, topping the podium across a 12-year span. Her heptathlon score is 1,400 points higher than the average career peak of #7 Martina Navratilova’s closest rival in multi-event scoring, showcasing an unbreakable benchmark in track and field.

Billie Jean King redefined sports activism, winning 39 Grand Slam titles—12 in singles, 16 in women’s doubles, and 11 in mixed doubles—while elevating tennis to a global platform. Her 1973 Battle of the Sexes victory over Bobby Riggs drew an estimated 90 million viewers worldwide, a broadcast audience 30% larger than the average Super Bowl of that decade. That single match outperforms #8 Nadia Comaneci’s perfect 10 viewership in reach, cementing King’s legacy as a cultural force beyond the court.

Martina Navratilova holds the all-time record of 167 singles titles, including 18 Grand Slam singles titles, a feat unmatched by any male or female player in tennis history. Her career win percentage of 86.8% in singles matches outranks #6 Billie Jean King’s 78.2%, a gap of 8.6 percentage points that underscores her sustained dominance over four decades from the 1970s through 2000s. She also claimed 59 Grand Slam titles across all disciplines, a total that is 51% higher than the typical career output of any top-10 tennis rival.

Nadia Comaneci made history at the 1976 Montreal Olympics by scoring the first perfect 10.0 in gymnastics at age 14, a feat that remains the benchmark for technical excellence in the sport. She won nine Olympic medals (five gold, three silver, one bronze) across 1976 and 1980, including three gold medals on the balance beam, an apparatus where her difficulty score averaged 9.95. Her perfect 10 is 15% more rare than #5 Jackie Joyner-Kersee’s world record in heptathlon, as no gymnast has repeated that flawless mark in Olympic team competition since.

Babe Didrikson Zaharias remains the most versatile female athlete in history, winning two Olympic gold medals in track and field at the 1932 Los Angeles Games—a feat unmatched by any multi-sport competitor except perhaps #10 Katie Ledecky in single-sport dominance. Her track success included a world record in the 80-meter hurdles (11.7 seconds) and gold in the javelin with a throw of 43.69 meters. She then transitioned to golf, winning 10 LPGA major championships and co-founding the LPGA in 1950, a unique career path that outperforms #9’s single-sport focus. Her 41 combined professional victories across sports make her faster than the average athlete in achieving elite status.

Katie Ledecky is the most dominant distance swimmer in history, with 7 Olympic gold medals and 21 World Championship gold medals—the most by any female swimmer, outperforming #9 Babe Didrikson Zaharias in pure medal count. She has broken 14 individual world records, including a staggering 800-meter freestyle time of 8:04.79, which is 30% faster than the runner-up’s best in that event. Her sustained excellence across four Olympics (2012–2024) is unmatched, as she holds the top 10 fastest times ever in the 1500-meter freestyle, a feat cheaper than the typical rival’s single-record career.
