Friedrich August, Duke of Holstein-Oldenburg (Gottorp, Schleswig, 20 September 1711 – Oldenburg, 6 July 1785) was the son of Christian August, Duke of Holstein-Gottorp and his wife Margravine Albertine Friederike of Baden-Durlach.
Frederick Augustus married Princess Ulrike Friederike Wilhelmine of Hesse-Kassel; the couple had three children:
Empress Catherine the Great of Russia, on behalf of her son Paul of Russia, last of the Dukes of Holstein-Gottorp, ceded the lands of that duchy to Denmark. In exchange, Denmark ceded the Duchy of Oldenburg to the Prince Bishops of Lübeck, a cadet branch of the Dukes of Gottorp. Thus, Friederich August of Holstein-Gottorp, Prince Bishop of Lübeck, became Duke of Oldenburg.
His son and heir apparent, Peter Friedrich Wilhelm, succeeded him as Wilhelm I, Duke of Oldenburg.
