The men's track time trial event at the 1980 Summer Olympics took place on 22 July 1980 in Moscow Olympic Velodrome. There were 18 competitors from 18 nations, with one additional cyclist entered but not starting. The event was won by Lothar Thoms of East Germany, the nation's second consecutive victory in the men's track time trial. Aleksandr Panfilov of the Soviet Union took silver, the nation's first medal in the event since 1960. David Weller's bronze remains—through the 2020 Games—Jamaica's only medal outside of track and field athletics. Denmark's three-Games medal streak ended.

The 1980 Summer Olympics, officially known as the Games of the XXII Olympiad and commonly known as Moscow 1980, were an international multi-sport event held from 19 July to 3 August 1980 in Moscow, Soviet Union, in present-day Russia. The games were the first to be staged in an Eastern Bloc country, as well as the first Olympic Games and only Summer Olympics to be held in a Slavic language-speaking country. They were also the only Summer Olympic Games to be held in a socialist state until the 2008 Summer Olympics held in China. These were the final Olympic Games under the IOC Presidency of Michael Morris, 3rd Baron Killanin, before he was succeeded by Juan Antonio Samaranch.
