The North American Lacrosse League (NALL) was a professional indoor lacrosse league based in the United States. It was founded in 2011 as North America's fourth professional lacrosse league, after American Lacrosse League (field lacrosse, 1987) Major League Lacrosse (a field lacrosse league) and the National Lacrosse League (the established professional indoor lacrosse organization). However, a rift in the organization led to the departure of four of the five teams to form the Professional Lacrosse League. After playing only one "full" season that was plagued with canceled games, a franchise folding, and players not showing up for games, the leagues folded.
