The Lone Star Football League (LSFL) was a regional professional indoor football minor league that played three seasons from 2012 to 2014. All of the LSFL's charter teams were based in the state of Texas, with five teams coming from the Southern Indoor Football League, three from the Indoor Football League, plus one expansion team. The LSFL played three seasons to completion before merging with the Champions Professional Indoor Football League in August 2014 to form Champions Indoor Football.
