Peter Friedrich Wilhelm, Duke of Oldenburg (3 January 1754 in Eutin Castle, Eutin – 2 July 1823 in Schloss Plön, Plön.) Wilhelm succeeded his father,Frederick Augustus I, Duke of Oldenburg as the Duke of Oldenburg in 1785. Wilhelm's mother was Princess Ulrike Friederike Wilhelmine of Hesse-Kassel.
Due to mental illness, Wilhelm was duke in name only, with his cousin Peter, Prince-Bishop of Lübeck, acting as regent throughout his entire reign.
The title became a Grand Duke in 1815, but Wilhelm never used the elevated style. It was not used until 1829 by the son of Wilhelm's cousin and successor, Peter I.
