People of the Saefkow-Jacob-Bästlein Organisation is a list of participants, associates and helpers of the Saefkow-Jacob-Bästlein Organization, which was one of the largest anti-Nazi resistance organisations that came into existence during World War II in Germany. It was formed in Berlin and had contacts to many other regions that hosted industrial manufacturing. 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 Bästlein organisation. The 506 people in the resistance organisation included about 200 before 1933 who were KPD members, 22 to the Social Democratic Party of Germany (SPD) or to the Socialist Workers' Party of Germany (SAP) and around 200 were non-party; one in four was a woman. 160 men and women were unionised before 1933, more than 60 of them in the German Metal Workers' Union (DMV).
