NCAA Division I men's lacrosse tournament

[1] From 1936 through 1970, the United States Intercollegiate Lacrosse Association (USILA) awarded the Wingate Memorial Trophy annually to the collegiate champion based on regular season records.

The first Division I Championship tournament held in 1971 replaced the USILA and Wingate Memorial Trophy national title awards.

In that span twelve teams — Johns Hopkins, Syracuse, Princeton, North Carolina, Virginia, Cornell, Duke, Maryland, Loyola University (Maryland), Denver, Yale and Notre Dame — have won the national title, with Syracuse leading with ten titles (plus one vacated by the NCAA[a]).

Only seven unseeded teams — the 1988 Cornell Big Red, the 1991 Towson Tigers, the 2006 Massachusetts Minutemen, the 2010 Notre Dame Fighting Irish, the 2011 and 2012 Maryland Terrapins and the 2016 North Carolina Tar Heels — have made it to the championship game, and only ten unseeded teams have made it to the tournament semi-finals, the most recent being North Carolina in 2016.

All three matches have always been scheduled for Memorial Day weekend, with the semifinals doubleheader on Saturday afternoon and the final held on the holiday itself.

Only eight schools from outside the Northeast/Mid-Atlantic have played in the NCAA tournament—Air Force, Butler, Denver, Marquette, Notre Dame, Ohio State, Michigan and Utah.

Of note several schools have claimed their Northern and Southern Division titles won during the USILL years as national championships (based on the results of 3 or 4 intra-division games), while others have not.
