Max Ilgner (born 28 June 1899 in Biebesheim am Rhein - died 28 March 1966 in Schwetzingen) 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 "spoilation and plunder", but released almost immediately, and continued his career as a political lobbyist and business executive, becoming chairman of a Swiss chemical company.
