The United States of America (USA), represented by the United States Olympic Committee (USOC), competed at the 2008 Summer Olympics in Beijing, China. U.S. athletes have competed in every Summer Olympic Games in the modern era, except the 1980 Summer Olympics in Moscow, which was boycotted by the American team and 65 other countries in protest of the Soviet invasion of Afghanistan. The USOC sent a total of 588 athletes to Beijing (310 men and 286 women), and competed in all Olympic sports except handball.
The USOC selected San Jose State University in San Jose, California, as the primary processing center for all Team USA members headed for Beijing 2008.
