Lacrosse
Lacrosse began as aa club sport at Trinity, when books about lacrosse were added to the College's library. In its beginnings, spring lacrosse was mainly for the purpose of keeping football players in shape for the fall season.
The first men's varsity intercollegiate system was established in 1961. Since then, Trinity men's lacrosse has made it to the NESCAC semifinals twice and to the NCAA tournament once.
Women's lacrosse played its first varsity season in 1975 and has been relatively successful since its founding. It has won four NIAC championships, five NESCAC championships, and one NCAA championship in 2012. Women's lacrosse has appeared in the NCAA finals five additional times.
