Hermann Michel (help·info), sometimes referred to as "Preacher" (born 23 April 1912), was a Nazi and SS-Oberscharführer (Staff Sergeant). During World War II, he participated in the extermination of Jews at the Sobibor extermination camp during the Nazi operation known as Aktion Reinhard. His current whereabouts is unknown.

Hermann Michel was born on April 23, 1912 in the Holzheim district of Bavaria, German Empire. In the mid 1930s, he began working as a male nurse at the Berlin-Buch medical center. By the late 1930s, along with Franz Stangl and Christian Wirth, he was working as a head nurse at Hartheim killing center, where the physically and mentally disabled were exterminated by gassing and lethal injection as part of the T-4 Euthanasia Program.

In April 1942, SS-Obersturmführer (First Lieutenant) Franz Stangl was appointed commander of Sobibor. Stangl appointed SS-Oberscharführer Hermann Michel as his deputy, due to their prior work relationship and his extensive experience in the enforced euthanasia programs.
