Marie Anne Mancini, Duchess of Bouillon (1649 – 20 June 1714), was an Italian-French aristocrat and cultural patron, the youngest of the five famous Mancini sisters, who along with two of their female Martinozzi cousins, were known at the court of Louis XIV, King of France as the Mazarinettes, because their uncle was the king's chief minister, Cardinal Mazarin.
