2017 League of Ireland First Division

The 2017 League of Ireland First Division season is the 33rd season of the League of Ireland First Division. The league began on 24 February 2017 and concludes on 7 October 2017. The 2017 season had no promotion/relegation play-off system like the previous years, only one team would be eligible for promotion whilst three teams would be relegated from the League of Ireland Premier Division in a revamp of the leagues by the FAI.

And returning to the League of Ireland Premier Division for the first time in 10 years was Waterford who won promotion with two games to spare as their 3–0 win over south east rivals Wexford coupled with nearest rivals Cobh Ramblers 3–0 defeat to Cabinteely secured the league title.

Overview
The First Division has 8 teams. Each team played each other four times, twice at home and twice away, for a total of 28 matches in the season.

On 22 December 2016, the FAI announced that the league would be restructured into two 10-team divisions from the 2018 season onwards, one of the recommendations made in the 2015 Conroy Report. This meant the cancellation of the promotion/relegation playoff and relegation at the end of the 2017 season of 3 teams from the Premier Division, with only the champions of the First Division promoted in return.
