Swimming at the 2012 Summer Olympics – Women's 200 metre individual medley

The women's 200 metre individual medley at the 2012 Summer Olympics took place on 30–31 July at the London Aquatics Centre in London, United Kingdom.

Despite of allegations of doping, China's Ye Shiwen pulled away from the rest of the field to strike a medley double for the fourth straight time in Olympic history since Michelle Smith did so in 1996, Yana Klochkova in 2000 and 2004, and Australia's Stephanie Rice in 2008. Coming from third at the final turn, she opened up her lead with a superb freestyle leg to establish a new Olympic record and a sterling gold-medal time in 2:07.57. Australia's Alicia Coutts produced a striking effort to claim the silver behind the Chinese teen in a lifetime best of 2:08.15, adding it to her Olympic hardware with a full set of medals. Meanwhile, U.S. swimmer Caitlin Leverenz stormed home on the rear of a dominant breaststroke leg to take the bronze in 2:08.95.

Rice, the defending Olympic champion, finished fourth in 2:09.55, while U.S. world record holder Ariana Kukors lost her chance to climb the podium with a fifth-place time in 2:09.83. Zimbabwe's Kirsty Coventry fell short in her second attempt for an Olympic medal, earning a sixth spot in 2:11.13. Great Britain's Hannah Miley (2:11.29) and Hungary's Katinka Hosszú (2:14.19) rounded out the field.

Earlier in the semifinals, Ye threw down a fastest freestyle split of 30.59 to set an Olympic record and a textile best in 2:08.39, cutting off Rice's previous standard by six-hundredths of a second (0.06) in a since-banned high tech bodysuit.
