The 14th IAAF World Championships in Athletics (Moscow 2013) () was an international athletics competition held in Moscow, Russia, from 10–18 August 2013. Initially, Russia won the most gold medals to top the table for the first time since 2001. It was also the first time ever the host nation took the top of the medal table. However, after disqualification of Russian sprinter Antonina Krivoshapka for doping and following redistribution of medals in the Women's 4 × 400 metres relay (as well as after series of other disqualifications of Russian athletes for doping offences), United States topped the medal table with eight golds. In the overall medal count, the United States won 26 medals in total, followed by Kenya with 12. With 1,784 athletes from 203 countries it was the biggest single sports event of the year. The number of spectators for the evening sessions was 268,548 surpassing Daegu 2011.
