Osters Idrottsforening, commonly known as Osters IF or simply Oster, is a Swedish sports club located in Vaxjo, specializing in football, and playing in the second tier of Swedish football, Superettan.
The club has previously also competed in ice hockey (see separate article), bandy, and bowling. Oster was formed on 20 April 1930 as Osters Fotbollforening, before adopting the name "Osters IF" in 1932. The club is affiliated to the Smalands Fotbollforbund.
In 1968, their first season in Allsvenskan, Oster became the first team ever to win the national title at their first attempt (newly-promoted IF Elfsborg won the league in 1961 but had played in, and been winners of, the championship in the past). This win ignited the team's 'golden age' which lasted until the early 1980s and saw them win a total of four Swedish championships.
On 31 March 2011, Oster broke ground on their new arena, Myresjohus Arena, which was inaugurated in August 2012. The arena hosted four games of the UEFA Women's Euro 2013 tournament.
