Ragnhild Nikoline Andersen (1907–1990) was a Danish trade unionist, politician, and a member of the Communist Party of Denmark (DKP). During the German occupation of Denmark in World War II, she was sent by the Gestapo to the Stutthof concentration camp near Gdansk in Poland, where she spent 20 months in dreadful conditions before being rescued. After the war, she was elected to the Folketing, becoming a member of DKP's central committee and one of the most prominent members of the party. She promoted wider access to abortions and improvements to women's rights.
