Erna Dickmann (or Dieckmann) (born August 16, 1912) was a female guard at several concentration and sub-camps in the last months of the Nazi Regime. She was born Erna Sowinski in Dortmund. She went to school and worked odd end jobs to support her and her family.

In 1944 Dickmann was conscripted to be a camp guard, and trained at the Flossenburg camp near Nuernberg, Germany. In the summer of 1944 she was assigned to the newly opened female subcamp in Zwodau , Czechoslovakia. Months later the SS again sent her to Holleischen to work as an Aufseherin. The middle aged female Nazi guard went to Neuengamme in November 1944 to work along side 50 or so other female guards and supervisors. In December, Erna was among several guards chosen to serve at the Bandorf subcamp in Germany.

She stayed there until the prisoners were evacuated to Bergen Belsen then returned home to Dortmund. She has never been tried for war crimes.
