The Sligo Football League is an annual Gaelic Athletic Association club league competition between the lower ranking Sligo clubs, operating in Division 3 of the league.
Since its inception in 1979 up to 2003, it was regarded as Division 2 of the league.
Since 2004 this has been altered, with a number of Intermediate teams playing in the higher Divisions (1A and 1B), and Division 2 itself was split in 2006, into Division 2A and Division 2B.
Enniscrone are the most successful club, having won on 4 occasions, the last in 2004.
Naomh Molaise Gaels, twice previous winners under their old incarnation as Grange/Cliffoney, won in 2008 after defeating St John's in the final.
