United States at the 2024 Summer Olympics

The United States of America (USA), represented by the United States Olympic & Paralympic Committee (USOPC), competed at the 2024 Summer Olympics in Paris from July 26 to August 11, 2024. U.S. athletes have appeared in every Summer Olympic Games of the modern era, except for the 1980 edition in Moscow, when America led a sixty-six-nation boycott in protest of the Soviet invasion of Afghanistan. As Los Angeles is hosting the 2028 Summer Olympics, the United States marched penultimately before the homebound French team entered Place du Trocadéro during the parade of nations segment of the opening ceremony. Additionally, an American segment featuring H.E.R. and Tom Cruise from Paris, and the Red Hot Chili Peppers, Billie Eilish, Snoop Dogg, and Dr. Dre from Long Beach, was performed during the closing ceremony.

The opening ceremony flag-bearers for the United States were LeBron James and Coco Gauff. James, a two-time Olympic gold medalist, is the first male basketball player to be chosen. At 20 years of age, Gauff is the youngest American athlete and the first tennis player to be so honored. The closing ceremony flag-bearers were Nick Mead and Katie Ledecky. Mead was part of the U.S. men's four rowing team that won their first gold medal since 1960, while Ledecky, a nine-time Olympic gold medalist, became the most decorated female Olympian to be chosen.
