Claressa Maria Shields is an American professional boxer and 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 November 2020, she is ranked as the world's best active female light middleweight by The Ring and BoxRec, as well as the best active female boxer, pound for pound and ESPN, second by The Ring, and fourth by BoxRec.

Shields is the only boxer in history, female or male, to hold all four major world titles in boxing—WBA, WBC, IBF and WBO—simultaneously, 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.
