The women's 400 metre individual medley event at the 2008 Olympic Games took place on 9–10 August at the Beijing National Aquatics Center in Beijing, China. Australia's Stephanie Rice pulled away to a strong finish on the freestyle leg, as she claimed an Olympic gold medal in the event. She established a sterling time of 4:29.45 to slash 1.67 seconds off the world record, set by Katie Hoff from the U.S. Olympic Trials. Zimbabwe's Kirsty Coventry also went under a world record, but earned her first silver at these Games, in an African record of 4:29.89. Meanwhile, Hoff did not match her stellar performance from the trials, as she settled only for the bronze in 4:31.71.
