Heinrich Schwarz (14 June 1906 – 20 March 1947) was an SS-Hauptsturmführer (captain) and concentration camp officer who served as commandant of Auschwitz III-Monowitz in Nazi-occupied Poland and Natzweiler-Struthof in Alsace-Lorraine.

Following the outbreak of World War II, Schwarz served with the Waffen-SS on the Western Front until October 1940, when he was transferred to the SS-Concentration Camps Inspectorate.

Central to the role Schwarz played as commandant was the provision of slave-labourers to the nearby Buna Werke, a synthetic rubber factory owned by the German chemical company IG Farben.

The brutal working conditions which prevailed at Monowitz during the period Schwarz served as commandant resulted in a large number of deaths among the inmate population, with estimates ranging between 10,000 and 35,000 prisoners who were believed to have died in the labour camp itself or in the gas chambers located at neighbouring Auschwitz-Birkenau.

Following the evacuation of Auschwitz complex on 18 January 1945, Schwarz was initially slated to take over command of the Mittelbau-Dora concentration camp and the associated V-weapons production facility of Mittelwerk, but was passed over for this post in favour of Richard Baer.
