Otto Max Koegel (16 October 1895 – 27 June 1946) was a Nazi officer who served as a commander at Lichtenburg, Ravensbrück, Majdanek and Flossenbürg concentration camps.

He went on to travel for work in Switzerland and Austria before returning to Füssen, where he obtained a job in his father's old furniture factory.

In 1929, Koegel's eight-year-old son died from measles and a short time later, his marriage of ten years ended in divorce.

From 1938 to 1942 he was first "Direktor" (managing director) and then commander of the labour camp for women in Lichtenburg at Ravensbrück at the rank of Sturmbannführer (Major).

In 1942 he was commander of the extermination camp Majdanek and was involved in the installation of gas chambers at this site.
