2011 World Championships in Athletics – Women's 4 × 100 metres relay

The Women's 4 × 100 metres relay event at the 2011 World Championships in Athletics was held at the Daegu Stadium on 4 September. Runners from the United States had provided the fastest times before the competition, but bad baton exchanges had seen their teams disqualified at both the 2008 Olympics and the 2009 World Championships. The Americans and Jamaica, the defending world relay champions, were seen as the primary contenders for the title. Ukraine and Russia (the Olympic title holder) were the next fastest entrants into the championships.
