Superettan (Swedish pronunciation: [ˈsʉ̂ːpɛrˌɛtːan]; meaning the super first (division)) is an association football league and the second highest league in the league system of Swedish men's football. Contested by 16 clubs, it operates on a system of promotion and relegation with Allsvenskan and Division 1. Seasons run from April to October, with teams playing 30 matches each, totalling 240 matches in the season.

Association football is the most popular sport in Sweden, with over 240,000 licensed players with another 240,000 youth players. There are around 3,200 active clubs fielding over 8,500 teams, which are playing on the 7,900 pitches available in the country. Football was first played in Sweden in the 1870s, the first championship was decided in 1896 and the Swedish Football Association was founded in 1904. Despite being a relatively small country population-wise, both the men's and women's national teams and the club teams have gained rather large success from time to time.
