The First 4 men's lacrosse invitational was an annual college lacrosse event held in California with the feature event being a double-header involving four NCAADivision I men's lacrosse teams. The event is representative of the recent expansion of the sport far afield from its traditional strongholds of Maryland and New York. The inaugural event took place at the Home Depot Center in Carson, California on March 12, 2005. It drew a crowd of 7,182 spectators. An event was planned for 2009, but cancelled due to a scheduling conflict and never resumed.
