Prince Paul of Yugoslavia, also known as Paul Karađorđević (Serbo-Croatian: Pavle Karađorđević, Serbian Cyrillic: Павле Карађорђевић, English transliteration: Paul Karageorgevich; 27 April 1893 – 14 September 1976), was regent of Yugoslavia during the minority of King Peter II. Peter was the eldest son of his first cousin Alexander I.

Prince Paul of Yugoslavia was the only son of Prince Arsen (brother of King Peter I) and Princess and Countess Aurora Pavlovna Demidova (a granddaughter of the Finnish philanthropist Aurora Karamzin and her Russian husband Prince and Count Pavel Nikolaievich Demidov, and Russian Prince Peter Troubetskoy and his wife Elisabeth Esperovna, née Princess Belosselsky-Belozersky). He married Princess Olga of Greece and Denmark, a sister of Princess Marina, Duchess of Kent, in 1923. King George VI, when Duke of York, was best man at his wedding in Belgrade.

Paul was educated at the University of Oxford, where he was a member of the exclusive Bullingdon Club - a dining club notorious for its wealthy members, grand banquets and boisterous rituals. Cultivated and bisexual like his closest friends Prince George, Duke of Kent and Sir Henry Channon, his outlook on life was said to be British. He was installed as a Knight of the Garter in 1939.
