Communist Party of Switzerland (Kommunistische Partei der Schweiz), known as the "Old Communists" (Altkommunisten), was a historical Communist party, section of the Communist International.
The Party originated from a group of left-wing socialists who were expelled from the Social Democratic Party of Switzerland in 1918. Fritz Platten was a central leader in the new Party. Bulgarian communist Solomon Goldstein was among the founders.
The Swiss Communist Party was banned in 1940 because of World War II. In 1944 some of its leading members founded the Swiss Party of Labour to replace the old Communist Party.
