Dr. Erhard Hübener (4 August 1881 – 3 June 1958) was a German politician and member of the German Democratic Party (DDP) until 1933. After World War II he engaged in rebuilding structures of self-rule in the Soviet occupation zone and was co-founder and member of the Liberal Democratic Party of Germany (LDPD).
Hübener was born in Tacken (now part of Groß Pankow (Prignitz)), Province of Brandenburg. His father was a Protestant pastor. After attending the school at Pforta, Hübener studied history and political science at Christian Albert's University, Kiel and Frederick William's University, Berlin. He graduated with a doctorate. Hübener and Otti Bornemann married in 1909. He served as an officer in World War I.
After the war he joined the liberal DDP. In 1919 Otto Fischbeck (DDP), Prussian minister of trade, gained him as a collaborator in the Prussian ministry of trade. In 1922 Hübener was elected vice land-captain of the Prussian Province of Saxony with Rudolf Oeser (*1858–1926*) serving as Saxon land-captain.
In 1924 the Saxon Provinziallandtag (provincial parliament) elected him Landeshauptmann (land-captain), the elected highest ranking representative of provincial self-rule. He distinguished himself as an expert in economics and administration, searching consensus among the representatives of the different parties.
