Peter Alexandrovich of Oldenburg (Peter Friedrich Georg von Holstein-Gottorp, Duke of Oldenburg) (21 November 1868 - 11 March 1924) was the first husband of Czar Nicholas II of Russia's youngest sibling, Grand Duchess Olga Alexandrovna of Russia and a member of the famed House of Oldenburg. The marriage ended in divorce on 16 October 1916, unconsumated and presumably due to Duke Peter being homosexual. He married a second time, on 3 May 1922, to Olga Vladimirovna Ratkova-Rognova (1878-1929). There were no children from either marriage.
