The Communist Party of Sweden (Kommunistiska Partiet) is a far-left Marxist-Leninist political party founded in 1970. It emerged from a series of splits within the Swedish communist movement during the late 1960s, when pro-Beijing factions broke away from the mainstream Left Party over ideological disagreements. Headquartered in Gothenburg, the party was officially registered in 1977 and adopted its current name at its 14th Party Congress in January 2005. As of March 2026, it held no seats in the Swedish parliament and did not contest national elections. The party historically has roots in the Maoist movement but has since distanced itself from that orientation. Its official organ is the weekly newspaper Proletären, which it has published since 1970.
