There were 12 competitors from 12 nations, with each nation limited to a single boat in the event. The event was won by Vyacheslav Ivanov of the Soviet Union, the nation's second consecutive victory in the men's single sculls. Ivanov was so thrilled when he was presented with his gold medal that he jumped up and down with joy-and dropped the medal into Lake Wendouree. He immediately dived into the lake to retrieve it, but couldn't find it. After the games were over he was given a replacement medal. Stuart Mackenzie took silver, making it the second consecutive Games with an Australian runner-up. American John B. Kelly Jr., after missing the finals in 1948 and 1952 by 0.4 seconds and 0.2 seconds respectively, reached the final and took the bronze medal this time.
