is an American former professional soccer player. She is a two-time Olympic gold medalist (2008 and 2012), two-time FIFA Women's World Cup champion (2015 and 2019), two-time FIFA Player of the Year (2015 and 2016), and a four-time Olympian (2008, 2012, 2016 and 2021). Lloyd scored the gold medal-winning goals in the finals of the 2008 Summer Olympics and the 2012 Summer Olympics. Lloyd also helped the United States win their titles at the 2015 and 2019 FIFA Women's World Cups, the bronze medal at the 2020 Summer Olympics, and she played for the team at the 2011 FIFA Women's World Cup where the U.S. finished in second place. After the 2020 Summer Olympics, Lloyd announced she would be retiring from the national team following four final friendly matches in 2021. Lloyd has made 316 appearances for the U.S. national team, placing her second in caps, and has the third-most goals and fifth-most assists for the team. In March 2021, she was named as the highest paid female soccer player in the world. She played her last international match with the USWNT on October 26, 2021, shortly before retiring from professional soccer at the completion of the 2021 NJ/NY Gotham FC season.

During the United States' 5–2 win over Japan in the 2015 FIFA Women's World Cup Final, Lloyd became the first player ever to score three goals in a FIFA Women's World Cup final and the second soccer player ever to score a hat-trick in any senior FIFA World Cup Final, after Geoff Hurst. Lloyd scored three goals in the first 16 minutes of the final, with the first two occurring in the first five minutes of the game and within three minutes of each other. She received the Golden Ball Trophy as the best player of the tournament and earned the Silver Boot for her six goals and one assist during the tournament.

She previously played for the Chicago Red Stars, Sky Blue FC (now known as NJ/NY Gotham FC), and Atlanta Beat in Women's Professional Soccer (WPS). In 2013, she was allocated to the Western New York Flash for the inaugural season of the National Women's Soccer League (NWSL) and helped her team win the regular season championship. After two seasons with the Flash, she was traded to Houston Dash prior to the 2015 season and then to Sky Blue before the 2018 season. Her memoir, When Nobody Was Watching, was published in September 2016.
