The women’s 4 × 100 metres relay competition at the 2012 Olympic Games in London took place on 9–10 August at the Olympic Stadium. The victorious United States team broke the world record by over half a second. The previous record had been set 27 years previously by East Germany a result that was widely considered suspicious due to East Germany’s record of doping. The Jamaican team 6 metres back missed the previous world record by .04 but set a new national record.
