Greece competed in the Olympic water polo tournament for the first time in 1920.

It is unclear why the Greeks received a place in the third-place tournament, as the Americans had not won either gold or silver, but Greece beat Italy in the quarterfinals of the bronze medal tournament before losing again to the United States in the bronze semifinals.

It was the nation's sixth appearance in athletics, having competed in the sport at every Olympics.

The Stockholm Games were only the second time that no Greek won a medal in athletics.
