Idrottsföreningen Kamraterna Östersund were founded on 7 March 1906 at the Café Temperance in Östersund. The club subsequently joined the IFK movement and specialised in a range of sports including football, bandy, ice hockey, handball, downhill skiing, cross country skiing, ski jumping, cycling, athletics, basketball, curling, boxing, wrestling, weightlifting and orienteering.
Since their foundation IFK Östersund has participated mainly in the upper and middle divisions of the Swedish football league system. The club's best period was in the 1950s and 1960s when they played a number of seasons in Division 2 Norrland which at that time was the second tier of Swedish football. The club currently plays in Division 3 Mellersta Norrland which is the fifth tier of Swedish football. They play their home matches at the Hofvallens IP in Östersund. The ground was first opened in 1917 but its current appearance reflects the work undertaken in 1936 when Hofvallen was redeveloped.
