This is a list of participants, associates and helpers of the Saefkow-Jacob-Bästlein Organization, which was one of the largest resistance organisation during World War II in Germany. It was formed in Berlin and had contacts to many other regions. It is therefore also referred to in the literature as the operational leadership of the Communist Party of Germany (KPD). However, it was not only communists among the groups of the Saefkov Jacob baker's organisation.
