Claressa Shields

Claressa Maria Shields (born March 17, 1995) is an American professional boxer and professional mixed martial artist. She has held multiple world championships in three weight classes, including the undisputed female light middleweight title since March 2021; the undisputed female middleweight title from 2019 to 2020; and the unified WBC and IBF female super middleweight titles from 2017 to 2018. Shields currently holds the record for becoming a two- and three-weight world champion in the fewest professional fights. As of October 2022, she is ranked the world's best active female middleweight by BoxRec, as well as the best active female boxer, pound for pound, by ESPN and The Ring.

Shields is one of only three boxers in history, female or male, to hold all four major world titles in boxing—WBA, WBC, IBF and WBO, in two weight classes.

In a decorated amateur career, Shields won gold medals in the women's middleweight division at the 2012 and 2016 Olympics, making her the first American boxer to win consecutive Olympic medals. Shields was the youngest boxer at the February 2012 U.S. Olympic Trials, winning the event in the 165 lb (75 kg) middleweight division. In May, she qualified for the 2012 Games, the first year in which women's boxing was an Olympic event, and went on to become the first American woman to win an Olympic gold medal in boxing. In 2018, the Boxing Writers Association of America named her the Female Fighter of the Year.

Shields is also a professional mixed martial artist, competing in the Professional Fighters League.
