NCAA Division I men's lacrosse tournament

The first Division I Championship tournament held in 1971 replaced the USILA and Wingate Memorial Trophy national title awards. As of 2023, 52 NCAA tournaments have been held (not held in 2020). 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]). In all, 41 teams have participated in the NCAA tournament since its inception. 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. Johns Hopkins has appeared in every tournament but three (1971, 2013, 2021). The Number One seed in the tournament has won the title 17 times and there have been 13 undefeated National Champions. North Carolina in 2016 was the first unseeded team to win the national title.

Originally consisting of eight teams, the size of the tournament field has changed over the years, increasing to 10 in 1986, 12 in 1987, 16 in 2003, 18 in 2014, down to 17 in 2017, down again to 16 in 2021, back up to 18 in 2022, and finally down to 17 in 2023. The two semifinal games and the final have been played on the same weekend at the same stadium since 1986. 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.

The sport has historically been focused in the Northeast and Mid-Atlantic states, with the sport's U.S. heartland today extending from New England to North Carolina. 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. No team west of the Eastern Time Zone won an NCAA championship until Denver in 2015.

20 coaches have won Division I titles: Richie Moran, Glenn Thiel, Bud Beardmore, Bob Scott, Henry Ciccarone, Willie Scroggs, Jr., Roy Simmons, Jr., Dave Klarmann, Don Zimmerman, Bill Tierney, Dom Starsia, John Desko, Dave Pietramala, John Danowski, Charley Toomey, John Tillman, Joe Breschi, Andy Shay, Lars Tiffany, and Kevin Corrigan. Tierney is the only one to have won at two different schools (Princeton and Denver).
