Elard Kurt Maria Fürchtegott von Oldenburg-Januschau (20 March 1855 – 16 August 1937) was a German Junker and conservative politician.

He embodied the prototype of the arch-conservative, militaristic and anti-democratic East Elbian Junkers both in the German Empire and in the Weimar Republic.

After the death of his brother Botho in 1882 he returned to his manor at Januschau and after his father died in 1885 Oldenburg also took over the ownership of Beisleiden.

He was an exponent of the antidemocratic conservatives and became well known for his dictum: "The King of Prussia and German Emperor must always be able say to a lieutenant: take ten men and lock up the Reichstag".

[2] Oldenburg was the only member of the Reichstag to defend Kaiser William II throughout the Daily Telegraph Affair and called the Social Democrats, who disturbed his speech, a "mob of pigs" (Schweinebande).
