Top 10 Most Successful Female Athletes of All Time

Simone Biles is the most decorated gymnast in World Championship history, with 37 World and Olympic medals including 23 golds — a record so far beyond her competitors that the sport introduced a scoring cap to prevent her from lapping the field entirely. Four gymnastics skills are named after her, each rated at the highest difficulty level, reflecting a combination of power, height, and precision that had never been seen before in women's gymnastics. Her decision to withdraw from multiple events at the 2020 Tokyo Olympics to protect her mental health sparked a global conversation about athlete wellbeing and is widely credited with changing how elite sport approaches psychological safety.

Mia Hamm retired in 2004 as the all-time leading international goal scorer in women's football history, with 158 goals in 276 appearances for the United States — a record that stood for over a decade. She won the FIFA World Cup twice (1991, 1999) and two Olympic gold medals (1996, 2004), and was named FIFA World Player of the Year in both 2001 and 2002, the first two years the award was given. Hamm's impact extended far beyond her statistics: she was the public face of the US women's team during its golden era and is widely credited with inspiring a generation of American girls to play sport, directly fuelling the post-Title IX surge in women's athletics.

Steffi Graf is the only tennis player in history — male or female — to win all four Grand Slam titles plus Olympic gold in a single calendar year, achieving the "Golden Slam" in 1988. She won 22 Grand Slam singles titles in total and held the world No. 1 ranking for a record 377 weeks — more than seven years — with 186 consecutive weeks at the top between 1987 and 1991 representing the longest uninterrupted run in the women's game. Graf's lethal forehand combined with relentless movement made her nearly unbeatable on every surface, and she remained the benchmark against which all subsequent female tennis players have been measured.

Martina Navratilova won 18 Grand Slam singles titles, 31 Grand Slam doubles titles, and 10 Grand Slam mixed doubles titles — 59 Grand Slam trophies in total, the most by any player in the history of the sport. She held the world No. 1 ranking for a combined 332 weeks and dominated professional tennis from the mid-1970s into the 1990s, winning Wimbledon nine times and pioneering the serve-and-volley game that redefined women's tennis tactics. Navratilova was the first prominent female athlete in a major team or individual sport to come out as gay while actively competing, in 1981, enduring significant commercial backlash and becoming a pioneering and permanently influential voice for LGBTQ+ rights in athletics.

Jackie Joyner-Kersee won six Olympic medals across the heptathlon and long jump, including three golds, and set a world record in the heptathlon of 7,291 points at the 1988 Seoul Olympics that still stands today — the most durable world record in any combined event in athletics history. Sports Illustrated named her the greatest female athlete of all time in 1999, citing the extraordinary range of speed, strength, and technique the heptathlon demands across seven disciplines. Joyner-Kersee competed throughout her career with severe exercise-induced asthma, keeping an inhaler at trackside and becoming a widely cited model of athletic will over physical adversity.

Billie Jean King won 39 Grand Slam titles across singles, doubles, and mixed doubles and held the world No. 1 ranking for five consecutive years from 1966 to 1970, establishing herself as the dominant force in women's tennis before the Open Era transformed the sport. Her 6-4, 6-3, 6-3 defeat of Bobby Riggs in the 1973 "Battle of the Sexes" — watched by 90 million people worldwide — became the defining sporting moment of second-wave feminism, proving beyond argument that women's sport deserved equal respect and coverage. King co-founded the Women's Tennis Association in 1973, championed the fight for equal prize money at the US Open — which was granted that same year — and remains the most important activist in the history of professional women's sport.

Annika Sorenstam won 90 LPGA Tour events — the second-highest total in women's professional golf history — including 10 major championships, and was the dominant force in women's golf for over a decade from the mid-1990s until her retirement in 2008. She is the only woman in the modern era to shoot a 59 in LPGA Tour competition, achieving the milestone at the Standard Register PING in 2001, and she held the world No. 1 ranking for a combined 60 career weeks at the top. In 2003, Sorenstam became the first woman in 58 years to compete in a PGA Tour event, shooting 71-74 at Colonial — a performance that brought women's golf its largest-ever television audience.

Nadia Comaneci became the first gymnast in Olympic history to be awarded a perfect score of 10.0, achieving this on the uneven bars at the 1976 Montreal Olympics at just 14 years old — and then scored six more perfect 10.0s at the same Games, winning three gold medals. The scoreboard had been designed to display a maximum of 9.9 and showed "1.00" when her score was registered, producing one of the most iconic images in Olympic broadcasting history. Comaneci won five Olympic gold medals in total across Montreal and the 1980 Moscow Games, and her Montreal performance is universally cited as the moment that permanently elevated artistic gymnastics from a niche sport to a global television spectacle.

Katarina Witt won two Olympic gold medals (Sarajevo 1984, Calgary 1988) and four World Championship titles, and was the only figure skater to win four consecutive World titles in the modern judging era — a record of consistency across the sport's most demanding decade. Competing for East Germany during the Cold War, her performances became politically charged cultural events watched by hundreds of millions in both East and West, and she attracted a level of global celebrity rare for any Olympic athlete in any era. Witt later competed at the 1994 Lillehammer Olympics as a professional, and her combination of athletic precision, theatrical charisma, and political context gave her a cultural footprint that extended far beyond the borders of figure skating.
