The Irish Premier Division is the top tier of professional football in Ireland. Established in 1985, it features a league format where teams compete for the championship title. The season typically runs from February to October, with each team playing 36 matches. The league consists of 10 teams, and the team with the most points at the end of the season is crowned the champion. The bottom teams face relegation to the First Division, while the top teams may qualify for European competitions, such as the UEFA Champions League or the UEFA Europa League.
