Swimming at the 1972 Summer Olympics – Women's 400 metre individual medley

The women's 400 metre individual medley event at the 1972 Summer Olympics took place August 31. This swimming event used medley swimming. Because an Olympic size swimming pool is 50 metres long, this race consisted of eight lengths of the pool. The first two lengths were swum using the butterfly stroke, the second pair with the backstroke, the third pair of lengths in breaststroke, and the final two were freestyle. Unlike other events using freestyle, swimmers could not use butterfly, backstroke, or breaststroke for the freestyle leg; most swimmers use the front crawl in freestyle events.
