Kaethe Hoern was a female SS supervisor at two concentration camps from 1944 until April 1945.

The details about Kaethe Hoern are unknown. We do not know where or when she was born, all we know is that she was born in Germany. In 1944, however, Kaethe arrived at Ravensbruck to begin her training as a female SS guard. She trained under Dorothea Binz, and soon became known among the female overseers as a "leader type." In the summer of 1944, Kaethe was given the title of Oberaufseherin in Ravensbruck, and assigned as head wardress to the Buchenwald subcamp near Allenburg , Germany. There she commanded up to twenty SS Aufseherin at one time, as well as over 400 women prisoners. In April 1945, Kaethe fled the Allendorf subcamp. In 1947 an American Tribunal tried the former head camp wardress for war crimes. Eventually she served seven years in prison for the maltreatment of concentration camp prisoners.
