François VI, Duc de La Rochefoucauld, Prince de Marcillac (French: [f??~swa d(?) la ???fuko]; 15 September 1613 – 17 March 1680) was a noted French author of maxims and memoirs.
It is said that his world-view was clear-eyed and urbane, and that he neither condemned human conduct nor sentimentally celebrated it.
Born in Paris on the Rue des Petits Champs, at a time when the royal court was vacillating between aiding the nobility and threatening it, he was considered an exemplar of the accomplished 17th-century nobleman.
Until 1650, he bore the title of Prince de Marcillac.
