NIFL Premiership

The NIFL Premiership, known as the Sports Direct Premiership for sponsorship purposes, and Irish Premiership colloquially, is a professional association football league which operates as the highest division of the Northern Ireland Football League – the national league in Northern Ireland. The NIFL Premiership was established as the IFA Premiership in 2008 under the auspices of the Irish Football Association as the successor to the Irish Premier League, before the Northern Ireland Football League was created for the start of the 2013–14 season. At the end of the season, the champion club is presented with the Gibson Cup.

Linfield are the current champions, winning their 9th title in the 2024–25 season.

The current format was introduced for the 2008–09 season after the league system for Northern Ireland was re-organised. The top flight was reduced in size from 16 to 12 clubs, included on the basis not only of their performance in the 2007–08 season, but in the previous two seasons, and other off-the-field criteria. Each applicant club was assessed by an independent panel and awarded points against the following criteria:

Portadown were the highest-profile casualty of the new system, suffering relegation to the newly formed IFA Championship as a result of submitting their application for inclusion in the Premiership 29 minutes past the deadline for consideration. The Northern Ireland Football League assumed responsibility for the top three divisions of Irish League national football from the IFA in 2014, putting forward plans to improve the scene of football in Northern Ireland. The plans include improving stadiums, status in European competitions, league structure, commercial image of the competitions, as well as spreading out match kick-off times to be more variable and reintroducing previously abandoned competitions for clubs to compete in, such as the Charity Shield, Floodlit Cup, Ulster Cup and Gold Cup.

Each team plays a total of 38 fixtures during the season. Each team initially plays every other team three times (either twice at home and once away, or once at home and twice away) for a total of 33 fixtures per team. The league then splits into Section A and Section B, the top six teams in Section A playing each other for a fourth and final time to settle championship and European qualification issues, and the bottom six teams in Section B playing each other to settle relegation issues. The post-split fixtures are usually arranged in such a way as to result in the teams in each half playing each other twice at home and twice away. After the split, teams in the top six cannot finish lower than 6th place, and teams in the bottom six cannot finish higher than 7th place, regardless of the results in the final 5 games. The Irish League campaign begins in August and continues until late April or early May. Most fixtures are played on Saturday afternoons, with occasional fixtures on Friday evenings, and some mid-week games, usually on Tuesday or Wednesday evenings. Traditionally, there are Bank Holiday afternoon fixtures on Boxing Day, New Year's Day, and Easter Tuesday.

Three points are awarded for a win, one point for a draw, and none for a loss. Points can be deducted for breaches of rules (e.g. fielding an ineligible player). The teams are first and foremost ranked by number of points, with the winner having the most points. If two or more teams finish level on points, four tiebreakers are used to separate them: highest overall goal difference, most goals scored, most points gained in the head-to-head meetings, and finally, highest goal difference in the head-to-head meetings. In the highly unlikely event that teams are still tied in a key position after these tiebreakers (e.g. determining the league champions, European qualification, relegation, or even second stage group allocation), lots will be drawn by the Management Committee.

There is no promotion from the Premiership, as it is the highest division of the Irish League system. At the end of the season, the 12th-placed club is relegated to the NIFL Championship and the 11th-placed club must take part in an aggregate two-legged play-off against the winners of the pre-play-off match between the runners-up and third-placed Championship teams. The away goals rule is applied after 90 minutes of the second leg, with extra time and penalties also used to determine the winner in the second leg if necessary. The Premiership club gets home advantage in the second leg, and is relegated to the Championship if it loses the tie. In the event that the Championship winners do not possess the Promotion licence required to be eligible for the top flight, there is no automatic relegation. Instead, the play-off is passed down to the 12th-placed Premiership club and the 11th-placed club is safe from relegation. In the event that there are no Championship clubs eligible for promotion, there is no relegation.

Northern Ireland is currently ranked in 42nd place out of 55 in the 2021 UEFA association coefficient rankings, which will be used to determine qualification places for the 2022–23 UEFA competitions. The Irish League’s relatively low ranking over the years has meant that the clubs have entered in the preliminary round or early qualifying rounds of UEFA competitions. No Premiership club has ever reached the group stage of a UEFA competition in their current respective formats. In fact, none have ventured beyond the second qualifying round of the Champions League. The closest any club has come to reaching the group stage was first during the 2019–20 UEFA Europa League, when Linfield became the first club from Northern Ireland to reach the play-off round, narrowly missing out on a place in the group stage after a 4–4 draw on aggregate against Qarabağ FK from Azerbaijan resulted in elimination on the away goals rule. Then, in the 2022–23 UEFA Europa Conference League play-off round, Linfield were beaten on penalties by FK RFS after a 3–3 draw on aggregate.
