Jeanne Bécu, Comtesse du Barry (French: [baʁi]; 19 August 1743 – 8 December 1793) was the last maîtresse-en-titre of King Louis XV of France. She was executed by guillotine during the French Revolution on accusations of treason—particularly being suspected of assisting émigrés to flee from the Revolution. She is also known as "Mademoiselle Vaubernier" ([vobɛʁnje]).
In 1768, when the king wished to make Jeanne maîtresse-en-titre, etiquette required her to be the wife of a high courtier, so she was hastily married on 1 September 1768 to Comte Guillaume du Barry. The wedding ceremony was accompanied by a false birth certificate created by Jean-Baptiste du Barry, the comte's older brother. The certificate made Jeanne appear younger by three years and obscured her poor background. Henceforth, she was recognised as the king's official paramour.
