The Grand Duchy of Oldenburg (German: Großherzogtum Oldenburg) (also known as Holstein-Oldenburg) was a grand duchy within the German Confederation, North German Confederation and German Empire which consisted of three widely separated territories: Oldenburg, Eutin and Birkenfeld. It ranked tenth among the German states and had one vote in the Bundesrat and three members in the Reichstag. Its ruling family, the House of Oldenburg, also came to rule in Denmark, Norway, Sweden, Greece and Russia. The heirs of a junior line of the Greek branch are, through Prince Philip, Duke of Edinburgh, in the line of succession to the thrones of the United Kingdom and the other Commonwealth realms after Queen Elizabeth II. As common for German houses, the ruling branch of Oldenburg, which ruled as Dukes and later Grand Dukes, holds the headship by primogeniture of the entire House of Holstein-Oldenburg with all its cadet branches.

Nikolaus, Hereditary Grand Duke of Oldenburg (German: Nikolaus Friedrich Wilhelm von Holstein-Gottorp, Erbgroßherzog von Oldenburg; 10 August 1897 – 3 April 1970) was the eldest son of Frederick Augustus II, Grand Duke of Oldenburg, who was the last ruling Grand Duke of Oldenburg. In 1931, Nikolaus succeeded to his father's titles and assumed the role of pretender to the Grand Duchy, until his death in 1970.
