Klaus-Peter Müller (born 16 September 1944 in Duppach, Germany) was chairman of the supervisory board of Commerzbank until the annual general meeting on 8 May 2018.

After finishing his apprenticeship at the Bankhaus Friedrich Simon [de] bank in Düsseldorf (1962–1964), he completed military service (1964–1966) in a number of roles, for example as a reserve officer candidate at Radio Andernach, the radio station of the Psychological Defence Force (Truppe für Psychologische Verteidigung [de]).

In the same year, Klaus-Peter Müller and major general Wolf Langheld, Commander of the First Armoured Division in Hanover, hosted the first Celler Trialog [de] forum calling for an intensification of cooperation between business, politics and Germany's armed forces.

[3] In April 2015, the German Federal Ministry of Defence assigned Müller the task of managing a group of experts that had been given the job of "searching for weaknesses in the organisational structure of the ministry and the Bundeswehr" in response to criticism of the G36 assault rifle, stating that his expertise qualified him for the role.

[19] Despite this, Klaus-Peter Müller still believes that the acquisition of Dresdner Bank was the right move; only the timing proved to be "unlucky" in retrospect.
