The World Lacrosse Men's U20 Championship, formerly known as the World Lacrosse Men's U19 Championship, are held every four years to award world championships for the under-20 age group in men's lacrosse. The tournaments are sanctioned by World Lacrosse.
These championships were first held for men in 1988. The 2008 men's championship was held in July 2008 in Coquitlam, British Columbia, Canada and was won by the United States. The 2012 men's tournament was held in Turku, Finland, with the United States winning the title, defeating Canada 10–8, despite a pair of pool-play losses to Canada and the Iroquois Nationals (now Haudenosaunee Nationals). The Iroquois Nationals finished third after an 18–1 win over England. The 2016 championship for men was held July 7–16, 2016, again in Coquitlam, British Columbia, just outside Vancouver. The U.S. won its eighth title, coming back from being down 6–0 to eventually defeat Canada 13–12.[1]
The 2020 competition was planned to be held as an under-19 tournament, but was postponed to 2021 as an under-20 tournament due to COVID-19 pandemic,[2] and then was postponed once again to 2022 as an under-21 tournament.[3] [4] The next tournament is planned to be held as an under-20 event in 2025.
