Arbeiterpolitik, Wochenzeitschrift für wissenschaftlichen Sozialismus (English: Labor Politics, The Weekly Journal for Scientific Socialism) was a German scientific socialist weekly newspaper, published by Johann Knief and others for a radical left-wing group of Social-Democrats, the Bremer Linksradikale, in Bremen from 1916 to 1919.
Among its notable contributors were Antonie Pannekoek and Otto Rühle.
The journal mostly wrote against the right wing and non-revolutionary tendencies of the SPD.
The magazine welcomed and defended the October Revolution.
In 1919, the group behind Arbeiterpolitik joined the Communist Party of Germany.
