The Men's Collegiate Lacrosse Association (MCLA) is a national organization of non-NCAA men's college lacrosse programs. The MCLA oversees game play and conducts national championships for over 200 teams in ten conferences throughout the United States and Canada. The MCLA provides a governing structure much like the NCAA, with eligibility rules, All-Americans and a national tournament to decide national champions in both Divisions I and II.

The MCLA exists to provide a quality college lacrosse experience where varsity NCAA lacrosse does not exist. On an individual scale, the MCLA provides rules and a structure that promotes "virtual varsity" lacrosse, or an experience paralleling that of NCAA programs. While the MCLA provides a high level of athletic competition, it is one of the few governing bodies that does not have a national GPA requirement for its athletes. On a national scale, the MCLA provides the infrastructure to support a level playing field through eligibility rules and enforcement and the use of NCAA rules of play. The MCLA, an organization governing a mere 70 teams in 1997, has seen a rapid growth in affiliation as national interest in the sport of lacrosse continues to increase. As of the 2014 season, participation has increased to 210 teams.
