Gertrud Elli Heise (born 23 July 1921) was a female guard and later, SS overseer at several concentration camps during the Second World War.

She remained there until she was assigned to guard the death march to KZ Auschwitz-Birkenau west, ahead of the Soviet offensive.

In November 1944, Heise was promoted to Oberaufseherin and sent to Obernheide,[5] the subcamp of KZ Neuengamme (Lagerbordell operated there since spring of 1944 with full staff).

[6] At Bremen-Obernheide, she and SS-Hauptscharführer Johann Hille,[7] commanded 500 Hungarian and 300 Polish women prisoners with a very high rate of deaths, regular beatings and denial of rations.

[8][9] Heise fled Obernheide in April 1945 with the evacuation of surviving women prisoners to Bergen-Belsen concentration camp.
