The Northern Ireland football league system is categorised into three levels: senior, intermediate and junior. Clubs attain intermediate status by fulfilling certain criteria (e.g. owning or leasing its own enclosed ground). Senior status requires clubs to reach stricter criteria. National leagues exist at senior and intermediate level. All junior leagues and some intermediate are organised on a regional basis.
Regionally, there are four regional football associations: the North East Ulster Football Association (also known as the County Antrim & District Football Association), the Mid-Ulster Football Association, the North West of Ireland Football Association and the Fermanagh & Western Football Association.
