Max Ilgner (28 June 1899 – 28 March 1966) was a German industrialist. He was a member of the board of IG Farben and held the title Wehrwirtschaftsführer or war economy leader under the Nazi regime. After the war, he was convicted by the Allies of "spoliation and plunder", but released almost immediately, and continued his career as a political lobbyist and business executive, becoming chairman of a Swiss chemical company.
