The Ulster Senior League was an association football league featuring amateur, intermediate, and League of Ireland reserve teams. Together with the Connacht Senior League, Leinster Senior League and the Munster Senior League, it formed the third level of the Republic of Ireland football league system. Ulster Senior League teams also competed in the FAI Cup and the FAI Intermediate Cup. The winners of the Ulster Senior League were also invited to play in the now defunct League of Ireland Cup. Despite using the Ulster name in its title, almost all of its clubs were based in County Donegal and the City of Derry. The most successful club in the league was Fanad United who won fourteen league titles and ten league cups. Since 2006 the USL had operated as a summer league with the season typically operating from April to October. In 2023, there were five teams competing in the league.
The league was dissolved in 2024 after the conclusion of the 2022/23 season, with its member clubs returning to junior football in the Inishowen and Donegal leagues.
