The men's 200 metre breaststroke was a swimming event held as part of the swimming at the 1920 Summer Olympics programme. It was the third appearance of the event. A total of 24 swimmers from 11 nations competed in the event, which was held from Thursday, August 26 to Sunday, August 29, 1920. Despite Erich Rademacher from Germany being one of the fastest breaststroker in the world at the time, he was not able to compete due to Germany's role in WWI. Despite this, he would establish his dominance in the event by laying consistent claim to the world record through most of the next decade.
