Eugen Müller (19 July 1891 – 24 April 1951) was a German general in the Wehrmacht during World War II.

He is known for having drafted the criminal Commissar order in preparation for Operation Barbarossa, the 1941 invasion of the Soviet Union.

1 September 1939, at the outbreak of World War II, Müller was assigned to the Headquarters Chief of Staff of the Army, under the command of Franz Halder.

[1] The paragraph in which General Müller called for Army commanders to prevent "excesses" was removed on the request of the OKW.

[2] The final draft of the order was issued by OKW on June 6, 1941, and was restricted only to the most senior commanders, who were instructed to inform their subordinates verbally.
