Lacrosse has been contested at two editions of the Summer Olympic Games, 1904 and 1908. Both times it had been open only to men; both times a Canadian team had won the competition. In its first year, three teams from two nations competed. The second appearance saw only two teams, again from two nations, compete. It was also held as a demonstration event at the 1928, 1932, and 1948 Summer Olympics. In 1948, the United States was represented by Rensselaer Polytechnic Institute (R.P.I.).
