# List of members of the Politburo of the Communist Party of Germany

This list provides an alphabetically ordered overview of the members and candidates of the Political Bureau (Polburo, later Politburo) of the Communist Party of Germany (KPD).
The formation of a political bureau (Polburo) was officially decided at the 7th Party Congress of the KPD (22–26 August 1921) in Jena. However, the KPD Zentrale had already set up a political bureau (Pol-Buro) and an organization bureau (Org-Buro) at the end of September 1920, as can be seen from the annual report to the 5th Party Congress.
On February 28, 1937, the Politburo of the Central Committee of the KPD in Moscow was dissolved and replaced by a four-member secretariat in Paris.
The representatives of the KJVD in the Politburo were not included here.
