2011 World Championships in Athletics – Women's 3000 metres steeplechase

The Women's 3000 metres steeplechase event at the 2011 World Championships in Athletics was held at the Daegu Stadium on August 27 and 30. The winning margin was 5.19 seconds which as of 2024 is the only time the women's 3000 metres steeplechase has been won by more than five seconds at these championships.

Milcah Chemos Cheywa was the pre-race favourite, having set the fastest time that year and gone undefeated on the Diamond League. Kenya also entered Mercy Wanjiku Njoroge and Lydia Jebet Rotich, the third and fourth fastest steeplechasers of the season. The other principal medal contenders were Sofia Assefa, second in the Diamond League rankings, and Yuliya Zarudneva (the 2009 runner-up). The 2008 Olympic champion Gulnara Galkina had failed to qualify, while the defending world champion Marta Domínguez was absent due to pregnancy.

On March 24, 2016, the Court of Arbitration for Sport disqualified Yuliya Zaripova's results from July 20, 2011 to July 25, 2013, which included the World Championships.

This resulted in the winning margin becoming 5.19 seconds. As of 2024, this is the only time this race has been won by more than five seconds at these championships.
