Krisztina Egerszegi (born August 16, 1974, Budapest, Hungary) is a former Hungarian swimmer and the youngest athlete ever to win an Olympic gold medal in swimming. She won the 200-meter backstroke at the 1988, 1992, and 1996 Olympic Games, becoming only the second swimmer (after Dawn Fraser) to win an individual event at three consecutive Olympiads.
In 1987 Egerszegi competed in her first international event at the European championships in Strasbourg, France, where she finished fifth in the 200-meter backstroke. At age 14 she became the youngest athlete ever to win an Olympic gold medal in swimming when she won the 200-meter backstroke at the 1988 Seoul Olympic Games; Egerszegi also won a silver medal in the 100 meters. In 1991, at age 16, she won both the 100- and 200-meter backstroke at the world championships in Perth, Western Australia. In that same year, she broke world records for both distances at the European championships in Athens.
At the 1992 Barcelona Olympic Games, Egerszegi won three gold medals, the most by any woman in individual events. She won the 400-meter individual medley and set Olympic records in both backstroke events. She was named Female World Swimmer of the Year in 1991 and 1992. In 1993 at the European championships in Sheffield, England, she was the first swimmer ever to earn four individual titles in a single European championship, winning the 100- and 200-meter backstroke, the 200-meter butterfly, and the 400-meter individual medley. Egerszegi returned to the Olympics at the 1996 Games in Atlanta. There she won a gold medal in the 200-meter backstroke and a bronze in the 400-meter individual medley.
Egerszegi announced her retirement from competitive swimming following the 1996 Games and was inducted into the International Swimming Hall of Fame in 2001.
