The League of Ireland Premier Division (Irish: Príomhroinn Sraith na hÉireann) is the top level division in the Republic of Ireland football league system. Contested by 12 clubs, it operates a system of promotion and relegation with the League of Ireland First Division. Seasons run from March to October, with teams playing 33 matches. Most games are played on Fridays, with a few games held on Saturdays and Sundays. Since 2010 the league is sponsored by SSE Airtricity and therefore officially known as the Airtricity League.
The division was formed as the League of Ireland Premier Division in 1985 as a result of the decision to split the League of Ireland into two divisions, which also created the League of Ireland First Division. The league is ranked 36th in the Union of European Football Associations (UEFA) coefficients of leagues based on performances in European competitions over the last five years, ahead of Lithuania's A Lyga and behind Moldova's National Division. In 2009, the FAI rejected proposals from clubs to remove the first division and restore the League of Ireland to its original structure.
Since 1921, a total of 19 clubs have been crowned champions of the Irish football league system. The current champions are Dundalk F.C., who won the title in the 2015 League of Ireland season.
