The League of Ireland 2004 season began on Friday 19 March 2004 and ended on Monday 22 November. This season was like a transitional one as one team was relegated from the Premier Division and three promoted from the First Division. This was done in order to increase the number in the Premier Division by two and reduce the First Division by the same amount. At the end of the season Shelbourne became league champions with Longford Town retaining the FAI Cup.
