Socialist League (in Swedish: Socialistiska Förbundet) was a Trotskyist organization in Sweden.
SF was founded on December 15, 1979 when the 'Bolshevik Fraction' was expelled from the Communist Workers League (KAF, later the Socialist Party).
In 1985 PT launched the Workers Association of Malmberget, which won a seat in Gällivare in the municipal elections.
PT, who had proposed a critical vote for the Social Democrats, refused to go along with this, and left to form the International Group.
As that project crumbled, the group originating from SF left it in 1993 and formed Workers List - Alternative.
