The NCAA Division II men's lacrosse tournament is the annual championship organized by the NCAA to determine the national champion of men's collegiate field lacrosse among its Division II programs in the United States.
The tournament has been played every year, except 2020, in two stints: first from 1974 to 1981 and then again from 1993 the present.
Before the implementation of a separate Division III tournament in 1979, the first five iterations of the event featured teams from both Divisions II and III.
During the eleven-year period (1982 to 1992) in which no Division II championship existed, all Division II men's lacrosse programs were allowed by the NCAA to compete as Division I members in that sport, and several D II teams received invitations to the Division I tournament during this period (Adelphi in 1982; C.W. Post in 1986; Adelphi again in 1987, where they upset Army; and Adelphi once more in 1989, where they received a number five seeding).
Adelphi have been the most successful program, with 8 national titles.
Adelphi are the reigning national champions, winning their record eighth national title in 2024.
