The Women's 4 × 400 metres relay event at the 2011 World Championships in Athletics was held at the Daegu Stadium on 2 and 3 September. Friday and Saturday. This is a change in schedule from previous years when all the relays were at the end of the program. This might necessitate a change in strategy to allow for team members involved in other events. On 21 June 2017, Russia forfeited the bronze medal following the disqualification of Kapachinskaya. The medal was reallocated by IAAF to Great Britain.
