Johann Schwarzhuber (29 August 1904 – 3 May 1947) was a Nazi German SS-Obersturmführer, who was in charge of various concentration subcamps during World War II.

His positions included the Schutzhaftlagerführer of the Auschwitz-Birkenau men's camp, where he oversaw the selection process for the gassing of thousands of detainees.

In front of the British military tribunal he was indicted for war crimes for his role in the Holocaust, sentenced to death and subsequently executed in 1947.

At the outbreak of World War II he was transferred to the Sachsenhausen concentration camp, where he acted as commander of the Klinkerwerk sub-camp.

With almost all of the Ravensbrück inmates being women, Schwarzhuber effectively commanded the entire complex, second only to overall camp leader Fritz Suhren.

The killings were so cruel, that several camp deputies refused to oversee the murders until Schwarzhuber took over and the executions proceeded uneventfully.

Thousands of women were killed in a newly built provisional gas chamber, coinciding with Schwarzhuber's arrival in the camp.
