The American Arena League (AAL) is a professional indoor football minor league that began playing in 2018. The league was initiated by a merger between Arena Pro Football (APF) and the Can-Am Indoor Football League (Can-Am), although the AAL only claimed the APF history after the former Can-Am founder left the league. Teams from both leagues, new teams, and later teams from Supreme Indoor Football and National Arena League constituted the new league for its inaugural season.
