Östersunds Fotbollsklubb, commonly known simply as Östersunds FK, Östersund (Swedish pronunciation: [œstɛˈʂɵnd]) or (especially locally) ÖFK, is a Swedish professional football club located in Östersund, Sweden. The club was formed in 1996 as a merger of several Östersund clubs. The club is affiliated to the Jämtland-Härjedalens Fotbollförbund and play their home games at Jämtkraft Arena. The club colours, reflected in their crest and kit, are black and red. Since its creation, the club has played mostly in the third tier of Swedish football but in 2013 Östersund achieved promotion to the second tier, Superettan, for the first time ever, after achieving two consecutive promotions, and since 2016 they played in the Swedish first tier, Allsvenskan.
Östersunds FK was created in 1996 when the three local clubs Ope IF, IFK Östersund and Östersund/Torvalla FF merged, aiming to create a club in that would be able to establish itself in the top two tiers of Swedish football. The next year Frösö IF also joined the project. The newly formed club started out their existence in the third tier in 1997 and Östersund/Torvalla FF ceased to exist as a consequence. IFK Östersund, Ope IF och Östersund/Torvalla FF (ÖTFF). In 2000 a fifth club, Fältjägarnas IF, was also merged into the club.
During the 2000s the club started taking on an English flavour and in 2007 the director of football Daniel Kindberg used his friendship with coaches Roberto Martínez and Graeme Jones to start a cooperation with Swansea City where Östersund would loan young players from the club. Swansea also came over to Östersund to play the inauguration game at the newly built stadium.
After a poor 2010 season the club was relegated to the fourth tier for the first time ever. The next year Daniel Kindberg returned to the role as director of football and increased financial backing from local companies which enabled the hiring of more full-time staff. The club also brought in young English manager Graham Potter who was working at an English university at the time. Through several successful signings, some coming from Potter's connections at Nike Football Academy, the club was able to win both the fourth tier and then the third tier immediately the year after. The club was promoted to Superettan for the 2013 season and finished 10th that season.
In January 2014 the club announced that they had signed a half-billion kronor deal with the government of Libya to develop and educate Libyan football players. Under the terms of the deal, Östersunds FK would train 250 young men from Libya every year, except the first year in which they will receive 60 students. Those players would be taught English and computer skills in addition to sports theory and football training. The deal was expected to raise Östersund FKs yearly profits by over 50%. The deal with the Libyan state never came to life, thus meaning no students came to Östersund and no money was received by the club.
On 27 October 2015, the club was promoted to Allsvenskan for the first time. In 2017, they managed to win their first major trophy, Svenska Cupen, after defeating IFK Norrköping 4–1 in the final, also qualifying for the 2017–18 UEFA Europa League, marking their first appearance in a European competition tournament. In their Europa League debut in the second qualifying round on 13 July 2017, Östersunds earned a shock 2–0 victory against Turkish giants Galatasaray at the Jämtkraft Arena and eliminated them after a 1–1 draw in Istanbul. Two goals by Saman Ghoddos in a win against PAOK on August 24 saw them qualify for the Group Stage at the first time of asking, at the same time making them the only Swedish representative in the season's UEFA competition and making Graham Potter the only British manager in the Europa League Group Stage. After losing only one game in their campaign, they finished second in a group featuring Athletic Bilbao and Hertha Berlin, becoming the first Swedish club to progress beyond the Europa League group stage.
This list of notable players includes those who have either been named player of the year at the club, or has become league top goalscorer, or went on to play in Allsvenskan (or for larger clubs abroad).
