International lacrosse

Lacrosse has been played for the most part in Canada and the United States, with small but dedicated lacrosse communities in Great Britain and Australia. Recently, however, lacrosse has begun to flourish at an international level with the sport establishing itself in many new and far-reaching countries, particularly in Europe and east Asia.

With lacrosse not having been an official Olympic sport since 1908, the pinnacle of international lacrosse competition consists of the quadrennial World Championships. Currently, there are world championships for lacrosse at senior men, senior women, under 19 men and under 19 women level. Until 1986, lacrosse world championships had only been contested by the United States, Canada, Six Nations, England and Australia, with Scotland and Wales also competing in the women's edition. The expansion of the game internationally saw the 2005 Women's World Cup competed for by ten nations, and the 2006 Men's World Championship was contested by 21 countries.

In 2003, the first World Indoor Lacrosse Championship was contested by six nations at four sites in Ontario, Canada. Canada won the championship in a final game against the Iroquois, 21-4. The 2007 WILC was held in Halifax, Canada on from May 14-20. Teams from Australia, Canada, the Czech Republic, England, Ireland, Iroquois Nationals, Scotland and the United States competed.

The next largest international field lacrosse competition is the European Lacrosse Championships. Held for both men and women, the European Lacrosse Federation (ELF) has been running the European Championships since 1995. Before 2001 the Championships were an annual event, but in 2001 the ELF changed the format to every four years between the World Championship. Before 2004, only 7 nations had ever participated, but in 2004 there was a record number of participating countries, with 12 men's and 6 women's, which made it the largest international lacrosse event of 2004. The last European Lacrosse Championships were held in Lahti, Finland in 2008, with 18 competing countries. England placed first with the Netherlands and Germany placing second and third, respectively.

The World Lacrosse Championships have been dominated by the United States, particularly in the men's game, where the only world championship game losses at either level was in the 1978 final to Canada and 2006 final to Canada. The USA has won 8 of the 10 senior men's and all six under 19 men's tournaments to date. The next Men's World Lacrosse Championships will be held in Manchester, England, in 2010. In the women's game, Australia have provided stiffer competition, even holding a winning record against the USA of 6 wins to 5 at senior world championships, plus one draw. Despite this, the USA has won 5 of the 7 senior women's and 2 of the 3 under 19 women's tournaments to date, with the other world championships won by Australia, including the 2005 senior women's trophy.

The Iroquois Nationals are a team consisting of members of the Six Nations of the Iroquois Confederacy. The team was admitted to the International Lacrosse Federation (ILF) in 1990. It is the only Native American team sanctioned to compete in any sport internationally. The Nationals placed fourth in the 1998, 2002 and 2006 World Lacrosse Championships.
