The Inishowen Football League (IOFL) is an amateur league for football clubs in the Inishowen peninsula of Ireland. There are three divisions, with a promotion-and-relegation system in operation. This three-division setup, introduced in 2016, replaced a structure that had been in place for twenty years. The season runs from late August to May. The league is featured in much of Inishowen's media, such as the Inish Times and the Inishowen Independent. The current champions are Aileach, who won the 2019-20 Premier Division season.
