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, the FAI Intermediate Cup and the Ulster Senior Cup (organised by the Ulster FA and known as the Knockalla Caravans Cup for sponsorship reasons). 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 with the only exceptions being Derry City and, very briefly, Monaghan United. The most successful club in the league was Fanad United who won fourteen league titles and ten league cups. The USL began life as a winter league but changed to a summer league between 2007 and 2016, with the season typically operating from April to October, before returning to a winter league until its demise in 2023.
By 2022, there were only five teams competing and the league folded after the conclusion of the 2022–23 season, with member clubs returning to junior football in the Inishowen and Donegal leagues.
