Participating nations

Athletes from 204 NOCs are expected to participate. The Netherlands Antilles Olympic Committee, which had planned to continue functioning after the dissolution of the Netherlands Antilles, had its membership withdrawn by the IOC Executive Committee at the IOC session of June 2011. However, Dutch Antillean athletes who qualify for the 2012 Olympics will be allowed to participate independently under the Olympic flag.[150] Listed below are NOCs who have qualified at least one athlete. As of 26 November 2011, 144 nations have qualified at least one athlete.
