Greece competed at the 1980 Summer Olympics in Moscow, USSR. Greek athletes have competed in every Summer Olympic Games. Of the four nations that have been to every Summer Games (the others being Australia, Great Britain, and Switzerland), Greece was the only one to compete under its national flag at Moscow, as the other three and several other nations competed under the Olympic flag (New Zealand flew the flag of the New Zealand Olympic and Commonwealth Games Association) in protest of the USSR's involvement in the Afghan Civil War.
