The 2017 IAAF World Championships, the sixteenth edition of the IAAF World Championships, were held from 4 to 13 August at London Stadium in London, United Kingdom. London was officially awarded the championships on 11 November 2011.

The London Stadium is a multi-purpose outdoor stadium at Queen Elizabeth Olympic Park in the Stratford district of London. It is located in the Lower Lea Valley, 6 miles (10 km) east of central London. The stadium was constructed specifically for the 2012 Summer Olympics and 2012 Summer Paralympics, serving as the Athletics venue and as the site of their opening and closing ceremonies. Following the Games, it was renovated for multi-purpose use and now serves primarily as the home of Premier League club West Ham United, who played at the Boleyn Ground before moving to the stadium in 2016.
