Gerda Steinhoff (29 January 1922 – 4 July 1946) was a Schutzstaffel (SS) Nazi concentration camp overseer following the 1939 German invasion of Poland.

On 1 October 1944, Steinhoff became a Blockleiterin, or block leader, in the Stutthof SK-III women's camp.

On 1 December 1944, Steinhoff was reassigned to the Stutthof Bromberg-Ost female subcamp located in Bydgoszcz, some 170km (105 miles) south of Danzig.

She was found guilty and convicted of crimes against humanity for her involvement in the selection process and her sadistic abuse of prisoners.

Sentenced to death, Gerda Steinhoff was publicly hanged with the other ten condemned camp personnel on 4 July 1946 on Biskupia Górka Hill near Gdańsk.
