Louis François Joseph de Bourbon or Louis François II, Prince of Conti (French pronunciation: [lwi fʁɑ̃swa ʒozɛf də buʁbɔ̃]; 1 September 1734 – 13 March 1814), was the last Prince of Conti, scion of a cadet branch of the House of Bourbon, whose senior branches ruled France until 1848.

After her death, his father retired from the Royal court to the Château de L'Isle-Adam, pursuing his love of hunting, although he would later emerge to have a distinguished military career.

In 1770 they were one of twelve couples invited to dine with the newlyweds, Louis XVI and Marie Antoinette, in the Opéra of the Palace of Versailles, which had been constructed for the royal wedding.

Louis François Joseph had two illegitimate children, born in 1761 and 1767, by Marie Anne Véronèse, known as Mademoiselle Coraline, previously a dancer at an Italian theatre.

He was banished to Spain along with his few remaining relatives who still lived in France and had not already been killed in the revolution, including Bathilde d'Orléans, Duchess of Bourbon.

Refusing to share in the plots of the Royalists, he lived an isolated existence in Barcelona until his death in 1814, whereupon the Princes of Conti became extinct.

During the reign of Louis Philippe I, he was removed from Saint-Michel and placed in the Chapelle royale de Dreux on 2 April 1844.
