The men's 200 metre breaststroke was a swimming event held as part of the swimming at the 1928 Summer Olympics programme. It was the fifth appearance of the event, which was established in 1908. The competition was held from Monday to Wednesday, 6 to 8 August 1928. Twenty-one swimmers from 13 nations competed. Coming into the event, Erich Rademacher from Germany was heavy favorite, as he had held the world record for several years despite not being able to compete at the 1920 and 1924 Olympics due to Germany's role in WWI. However, Yoshiyuki Tsuruta pulled off an upset by beating Rademacher with a new technique of staying underwater for most of the race, which was allowed in the rules at the time. Despite this, Rademacher's disappointment was short lived, as he later won gold as the goalkeeper for the German water polo team in the men's water polo.
