|Lacrosse at the Summer Olympics|
|Governing body||World Lacrosse|
Lacrosse at the Summer Olympics has been contested at two editions of the Summer Olympic Games, 1904 and 1908. Both times a Canadian team won the competition. In its first year, two teams from Canada and one team from the United States competed at the games in St. Louis, Missouri. Only two teams, one from Canada and one from Great Britain competed in 1908 in London.
Lacrosse was also held as a demonstration event at the 1928, 1932, and 1948 Summer Olympics. In 1928 and 1932 the United States was represented by the Johns Hopkins Blue Jays men's lacrosse team, and in 1948 by Rensselaer Polytechnic Institute (R.P.I.). Canada sent an all-star team in 1928 and 1932; Great Britain sent an all-star team in 1928 and 1948.

Every team that has played lacrosse has won a medal. Canada has won three of the five medals, by virtue of having had three of the five competing teams.
