Baseball at the 1956 Summer Olympics

Baseball at the 1956 Summer Olympics was a demonstration sport at the 1956 Summer Olympics in Melbourne. Though it was nominally the "foreign" demonstration sport of that Olympiad, Australia had a long history of baseball dating back to at least 1889. The Australians fielded a full team in an exhibition match against the United States, represented by a detachment from the United States Far East Command. Many Sheffield Shield cricket players – who were quite successful at baseball as a winter sport – were unable to be selected on the basis that they were professional players.

Held at the Melbourne Cricket Ground, the game was notable for its high turnout; at the time, it was thought to be the largest audience for a baseball game in history, though the exact number of spectators remains in question.
