Claressa Maria Shields (born March 17, 1995) is an American professional boxer and former professional mixed martial artist. She has held 18 major world championships spanning five weight classes, including the undisputed female light middleweight title in March 2021; the undisputed female middleweight title twice between 2019 and 2024; the World Boxing Council (WBC) and International Boxing Federation (IBF) female super middleweight titles from 2017 to 2018; the World Boxing Organization (WBO) female light heavyweight title from 2024 to 2025 and the undisputed female heavyweight title since February 2025. Shields currently holds the record for becoming a two, three, four and five division world champion in the fewest professional fights. As of August 12, 2025, she is ranked the world's best active female light heavyweight by BoxRec, as well as the best active female boxer, pound for pound, by ESPN and The Ring.
Shields is the only female boxer in history to hold all four major world titles in boxing—WBA, WBC, IBF and WBO, in three weight classes. She is also the third (Amanda Serrano, Naoko Fujioka) female boxer in history to become champion in five different divisions.
In a decorated amateur boxing 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 middleweight division.Barnas, Jo-Ann.

Following Shields' victory at the U.S. Olympic Trials, it was initially reported that she would need only a top-8 finish at the 2012 AIBA Women's World Boxing Championships in Qinhuangdao, China, in order to qualify for the 2012 Olympics.
On May 10, the day after the contest began but before Shields' first bout, a change to the rules was announced that meant Shields would need to place in the top two from the (North, Central, and South) American Boxing Confederation region of AIBA (AMBC).Barnas, Jo-Ann.

Shields won her first round but was beaten in the second round on May 13 to Savannah Marshall of England, bringing Shields' record to 26–1.
Her chances for qualification thus depended on Marshall's subsequent performance; after Marshall advanced to the middleweight finals on May 18, it was announced that Shields had earned an Olympic berth. At the 2012 Summer Olympics in London, aged 17, she won the gold medal in the women's middleweight division after beating veteran Russian boxer Nadezda Torlopova 19–12. This made her the first American woman to win a boxing gold medal.

On June 16, 2017, Shields headlined the "Detroit Brawl," facing Sydney LeBlanc in her first scheduled eight-round bout. LeBlanc signed on with three days notice, after Mery Rancier dropped out due to visa issues. Shields won the bout by decision after all eight rounds.

Shields won via unanimous decision with two judges scoring the fight 97–93 and one scoring it 96–94, all in favor of Shields to become the undisputed middleweight world champion.

Her second bout was initially scheduled to take place on the PFL 9 event on August 27, 2021, against an opponent yet to be named. However, on July 12, 2021, news surfaced that her bout was rescheduled to take place on August 19, 2021, in order to garner more exposure at an ESPN-aired PFL 8 event. It was eventually rescheduled for PFL 10 on October 27, 2021, with Shields facing Abigail Montes. Shields lost the bout via split decision.
