The 2011 NCAA Division I Men's Lacrosse Championship was the 41st annual single-elimination tournament to determine the national championship for National Collegiate Athletic Association (NCAA) Division I men's college lacrosse. Sixteen teams were selected to compete in the tournament based upon their performance during the regular season, and for some, by means of a conference tournament.
The championship game took place on May 30, 2011 at M&T Bank Stadium in Baltimore, Maryland, where Virginia won its fifth NCAA lacrosse championship and seventh college title overall, defeating Maryland 9-7 in the title game. Maryland became only the fourth unseeded team to reach the finals and the second unseeded in a row. This was the first all-ACC title game since the 1986 championship. 
During the tournament, Virginia head coach Dom Starsia became the winningest coach in Division I men's lacrosse history, earning his 327th career win in the quarterfinals against Cornell, surpassing Jack Emmer's record of 326. In addition, the first-round match between Denver and Villanova, held at Peter Barton Lacrosse Stadium on the DU campus on May 15, was historically notable as the first Division I men's tournament game ever to be held west of the Mississippi River.
