Prince Bernadotte is a title that has been used by several members of the House of Bernadotte. It is most commonly known as a title granted to men who were formerly titled as princes of Sweden before losing their royal titles when they married unequally and against the Swedish constitution. It was created in 1892 as a non-hereditary title in the nobility of Luxembourg and conferred upon Oscar Bernadotte by Adolphe, Grand Duke of Luxembourg. A title with the same name was subsequently created in 1937 as a non-hereditary title in the nobility of Belgium and conferred upon Carl Bernadotte by King Leopold III of Belgium. The wives of these princes of Luxembourgish and Belgian nobility were then granted the title of Princess Bernadotte. The title was also used in the early 19th century with reference to Jean Baptiste Jules Bernadotte, the subsequent founder of the Swedish royal House of Bernadotte.

The House of Bernadotte is the royal family of Sweden, founded there in 1818 by King Charles XIV John of Sweden. It was also the royal family of Norway between 1818 and 1905. Its founder was born in Pau in southern France as Jean Bernadotte. Bernadotte, who had been made a General of Division and Minister of War for his service in the French Army during the French Revolution, and Marshal of the French Empire and Prince of Ponte Corvo under Napoleon, was adopted by the elderly King Charles XIII of Sweden, who had no other heir and whose Holstein-Gottorp branch of the House of Oldenburg thus was soon to be extinct on the Swedish throne. The current king of Sweden, Carl XVI Gustaf, is a direct descendant of Charles XIV John.
