The Third Marx cabinet (German: Drittes Kabinett Marx) was the 14th democratically elected Reichsregierung of the German Reich, during the period in which it is now usually referred to as the Weimar Republic. The cabinet was named after Reichskanzler (chancellor) Wilhelm Marx and was in office for only seven months. On 17 May 1926 it replaced the Second Luther cabinet after the resignation of Hans Luther on 13 May 1926. Marx resigned with his cabinet on 17 December 1926 but remained in office as caretaker. He formed another government on 29 January 1927.
