The League was dissolved in 2024, with the member clubs returning to junior football in Inishowen and Donegal leagues.[2]
History
The Ulster Senior League was formed in 1986. The driving force behind the establishment of the league was Fr. Michael Sweeney, a pioneer of junior and intermediate association football in County Donegal. In addition to founding the USL, Sweeney had earlier been instrumental in both establishing the Donegal League and forming Fanad United.[3][4] Fanad United were the inaugural USL champions in 1986–87 and they subsequently went on to become the league's most successful club, winning fourteen league titles and ten league cups. In more recent seasons, Cockhill Celtic have challenged Fanad United's dominance, winning their first title in 2010 and then nine consecutive titles between 2013 and 2022.[5][6] The winners of the Ulster Senior League have regularly been invited to participate in the League of Ireland Cup. In 1987–88 Fanad United were semi-finalists. Cockhill Celtic, Culdaff and Swilly Rovers have all represented the USL in the League of Ireland Cup.[4][7] Fanad United have also won the FAI Intermediate Cup twice while Letterkenny Rovers were finalists in 2015–16.[8][9]
September 2020 saw the leagues most successful club, Fanad United, announce their withdrawal from the USL to join the Donegal Junior League[10]
2021 saw Monaghan United F.C., a former League of Ireland club, join the Ulster Senior League, the first club from Counties Cavan or Monaghan to do so.[11] They withdrew from the league after just one season.[12]
The Ulster Senior League Cup has had four different sponsors since first being played for in 1986–87. Initially, the competition was sponsored by the Hotel Glenveagh in Gweedore before being sponsored by Hydro Seafoods and then Marine Harvest. It is now known as the Donegal News Ulster Senior League Cup.[6]
