Lacrosse has been held in two Olympic Games, St Louis 1904 and London 1908. Both times it was open only to men and both times a Canadian team won the gold medal. At St Louis 1904, three teams from United States and Canada competed with Canadian team Shamrock triumphing. The second appearance, at London four years later, saw only two teams, from Canada and Great Britain, compete. Lacrosse was also held as a demonstration event at Amsterdam 1928, Los Angeles 1932 and London 1948.
