Germany competed at the 2008 Summer Olympics in Beijing, People's Republic of China. A total of 439 athletes were nominated to participate in the Games. The German Olympic Sports Confederation nominated athletes on 29 May, 23 June and 15 July 2008. Reaching the qualification standard set by the relevant sport's international governing body did not automatically mean that the athlete was nominated for Beijing, as the DOSB had stricter qualification standards. An athlete needed to have a somewhat realistic chance for a top 12 position. An exception to this are the team events, as the number of competing teams is already very limited through the IOC standards, and a chance for a respective place is already given by the qualification.
