2004 Athens Games, 2008 Beijing Games, 2012 London Games
Medal count: Three golds, four silvers, five bronzes
In 2008, Coughlin became the first woman to defend gold in the 100-meter backstroke. Her six medals that year gave her the record for most by a woman in a single Olympiad. Her only medal in 2012 was a bronze for the 4x100 freestyle relay, but she's eying a return in 2016.
