The Scottish Football League (SFL) was a league featuring professional and semi-professional football clubs mostly from Scotland. From its foundation in 1890 until the breakaway Scottish Premier League (SPL) was formed in 1998, the SFL was the top level of football in Scotland. After 1998, the SFL represented levels 2 to 4 of the Scottish football league system. In June 2013, the SFL merged with the SPL to form the Scottish Professional Football League.
