The 2013–14 NIFL Premiership (known as the Danske Bank Premiership for sponsorship reasons) was the sixth season of Northern Ireland's national football league in this format since its inception in 2008, the 113th season of Irish league football overall, and the first season of the league under the control of the Northern Ireland Football League, who took over from the Irish Football Association (IFA). The season began on 10 August 2013, and concluded on 26 April 2014.
After successfully gaining the required Championship Club Licence from the IFA, 2012–13 Championship 1 winners Ards were promoted to this season's Premiership. The club returned to the top flight for the first time since they were relegated in the 2005–06 season. After 11 years in the top flight, last season's bottom-placed Premiership club Lisburn Distillery were relegated to intermediate football for the first time in their history, bringing to an end their record of being one of only four clubs to have retained membership of the senior Irish League since its inception in 1890.
The runners-up of Championship 1, Warrenpoint Town, faced last season's 11th-placed club Donegal Celtic in the promotion/relegation play-off to decide which club would take the final place in this season's Premiership. The tie ended 2–2 on aggregate, with Warrenpoint Town winning on the away goals rule to secure promotion to the top flight of national football for the first time in their history – the club's third promotion in four years.
Ards nominated Bangor's home ground, Clandeboye Park, as the venue for their home games as they had been without a home ground since 2002. However, as a result of construction work being carried out to the ground, their first four home matches of the season were played at Dixon Park – the home of Championship side Ballyclare Comrades. The other newly promoted side, Warrenpoint Town, played some of their home fixtures at Dungannon Swifts' ground, Stangmore Park. This was due to improvements being carried out at their own ground, Milltown, in order to upgrade it to Premiership standard. However, the first ever Premiership game to be played at the ground, which was against Glenavon, was abandoned during half-time due to floodlight failure. The first completed fixture at the ground was a 2–0 win over Ards on 26 December 2013. That match also experienced floodlight problems, delaying kick-off for the second half by 20 minutes.
During matches 34–38 each team played every other team in their half of the table once. As this was the fourth time that teams had played each other this season, home sides were chosen so that they had played each other twice at home and twice away.
For the 2013–14 UEFA competitions, the associations were allocated places according to their 2012 UEFA country coefficients, which took into account their performance in European competitions from 2007–08 to 2011–12. In the 2012 rankings used for this season's European competitions, Northern Ireland's coefficient points total was 2.583. After earning a score of 0.500 during the 2011–12 European campaign, the league was ranked by UEFA as the 48th best league in Europe out of 53 - up one place from 49th the previous season. This season Northern Ireland earned 0.875 points, which was added to the points total for the 2014 rankings used in 2015–16 UEFA competitions.
After winning the league last season, Cliftonville were the sole representatives in the 2013–14 UEFA Champions League. They entered the draw in the second qualifying round. The draw to discover their opponents took place on 24 June 2013, and Cliftonville were rewarded with a dream tie against Scottish giants, Celtic. The first leg took place at Solitude on 17 July 2013, and Celtic earned a comfortable 3–0 win. The second leg was played at Celtic Park on 23 July 2013, with Celtic winning 2–0 for a comfortable 5–0 aggregate victory.
2012–13 League runners-up Crusaders, third-placed Linfield, and Irish Cup winners Glentoran all earned a place in the UEFA Europa League. They entered the draw at the first qualifying round. The draw to discover their opponents took place on 24 June 2013. Glentoran were paired against KR of Iceland while Linfield faced ÍF Fuglafjørður from the Faroe Islands. For the second consecutive season, Crusaders were drawn to play Rosenborg of Norway, the team they lost 4–0 on aggregate to at the same stage of last season's competition. Crusaders played the first leg at home on 4 July 2013 and went down 2–1 to Rosenborg, having led the match 1–0. In the second leg, Crusaders were well beaten 7–2 away from home, crashing out of the competition 9–3 on aggregate. Glentoran were away from home for the first leg and came away with a respectable 0–0 draw, however in the second leg at home they were disappointingly defeated 3–0 and exited the competition 3–0 on aggregate.
Linfield played their first leg in the Faroe Islands on 3 July 2013, and came away with a 2–0 victory. This was the club's first European away win in 47 years, since a 4–1 victory away to Vålerengen in the second round of the 1966–67 European Cup. In the second leg, Linfield won 3–0 to go through to the next round 5–0 on aggregate - the first time in the club's history that they had won both legs of a European tie. After the exit of both Crusaders and Glentoran from the competition, this left Linfield as the league's only representative in the second qualifying round. They faced Greek side Xanthi in the next round. Despite being massive underdogs for the tie, a 1–0 victory in the away leg made it three consecutive victories for Linfield in Europe, without conceding a goal in the process - another first for the club. However, in the second leg at home they went down 2–1 after extra time, which eliminated them on the away goals rule.
