The United States of America (USA), represented by the United States Olympic Committee (USOC), competed at the 2012 Summer Olympics in London, from July 27 to August 12, 2012. U.S. athletes have competed at every Summer Olympic Games in the modern era, except the 1980 Summer Olympics in Moscow which they boycotted in protest of the Soviet invasion of Afghanistan. The USOC sent a total of 530 athletes to the Games, 262 men and 268 women, to compete in 25 sports. For the first time in its Olympic history, the United States was represented by more female than male athletes.
U.S. athletes left London with a total of 105 medals (48 gold, 26 silver and 31 bronze), finishing at the top of the gold and overall medal standings. The 48-gold medal record was the most the United States had ever won in any Olympics in which it was not the host nation. At least one medal was awarded to U.S. athletes in sixteen sports, thirteen of which contained at least one gold. U.S. athletes dominated the nations' medal standings in swimming, wherein they won a total of 31 medals, including 16 golds. Twenty-seven U.S. athletes won more than a single medal. The U.S. team-based athletes also proved particularly successful, as the women's soccer, water polo, and volleyball teams won gold and silver medals, respectively. Furthermore, the men's and women's basketball teams managed to defend their titles from Beijing. For the first time since 1936, no U.S. athlete won an Olympic medal in sailing.
Among the nation's medalists were swimmers Missy Franklin, Allison Schmitt and Ryan Lochte, who each won a total of five medals. Swimmer Nathan Adrian and platform diver David Boudia won gold medals in their respective individual events after 24-year-long non-successes. Meanwhile, tennis player Serena Williams followed her sister's success by winning the gold medal in the women's tennis singles event. Gymnast Gabby Douglas became the fourth U.S. female to win a gold medal in the individual all-around event. Allyson Felix became the most successful U.S. track-and-field athlete at the event, winning three gold medals. Swimmer Michael Phelps emerged as the most decorated athlete in Olympic history, with a total of 22 medals won (including four gold and two silver medals in London) â 18 gold, 2 silver and 2 bronze medals â surpassing Larisa Latynina's overall Olympic medal count.
After the disqualification of Russian Ivan Ukhov for doping, Erik Kynard has finally got upgraded from silver to gold, which makes it the 47th US gold medal at these Games, the best American result in terms of gold medals in the Summer Olympics held outside of the United States. Ten years later, Lashinda Demus was promoted to the gold medal as well after another Russian, Natalya Antyukh, was found guilty of doping, bringing the total to 48 gold medals.
The following U.S. competitors won medals at the games. In the by discipline sections below, medalists' names are bolded.

One hundred and forty-three athletes were two-time Olympians, including former defending champions Justin Gatlin (athletics) and Anthony Ervin (swimming), who both made their comeback in London after long years of absence. Two hundred and eight returning athletes had competed in Beijing, including 124 Olympic medalists, and 76 defending champions.
Among the nation's defending champions were swimmers Michael Phelps and Natalie Coughlin. Phelps won a historic amount of eight gold medals in Beijing to become the most-decorated Olympic athlete at a single event and the first person to win a total of fourteen Olympic gold medals. Coughlin, on the other hand, won a total of 11 Olympic medals in two previous games, including six gold medals from Beijing. Other notable defending champions featured basketball players Kobe Bryant and LeBron James, who led their team by recapturing the nation's gold medal in Beijing, shooters Walton Eller and Vincent Hancock, road cyclist Kristin Armstrong in women's time trial, and swimmers Rebecca Soni and Ryan Lochte.
First-time Olympians also featured gymnasts Jordyn Wieber and Aly Raisman, decathlete Ashton Eaton, and swimmers Missy Franklin and Katie Ledecky, the youngest of the team at age 15.

The 2012 US Olympic team uniforms for opening ceremony of the London Olympics were designed by American clothing brand Ralph Lauren, but were manufactured in China, setting off a bipartisan backlash from the United States Congress protesting US manufacturing not being showcased by the US Olympic athletes.
On July 13, 2012, six Democratic U.S. senators announced they had co-sponsored legislation to require the 2012 U.S. Olympic team to wear US-made uniforms. The co-sponsors of the "Team USA Made In America Act of 2012" are Senators Robert Menendez and Frank R. Lautenberg, both of New Jersey, Bob Casey of Pennsylvania, Sherrod Brown of Ohio, and Charles E. Schumer and Kirsten Gillibrand of New York.
Due to uniform controversy for the summer games, on July 13, 2012, The U.S. Olympic Committee stated that the uniforms for the opening and closing ceremonies at the 2014 Winter Olympics, in Sochi, Russia, will be made in the United States.
