American Dana Vollmer was back to defend her Olympic title, but the heavy favorite in this event was Sweden’s Sarah Sjoström. Sjoström had won three of the last four world titles in the event and had posted the five fastest times in history. Vollmer had retired after the London Olympics and had a baby in March 2015, but elected to return for Rio. Other potential medalists were Australia’s Emma McKeon, China’s Chen Xinyi, and Denmark’s Jeanette Ottesen Gray.

Sjoström did not disappoint, winning the gold medal with a world record of 55.48 in the final. Over a second behind was Canadian Penny Oleksiak, the break-out swimmer of the Rio Olympics, who would also win an individual gold medal in the 100 freestyle. Vollmer came through for the bronze medal.
