Louis François de Boufflers, Duke of Boufflers was a prominent French soldier in the age of Louis XIV of France. He was created count of Cagny and duke of Boufflers and named marshal of France. He was famed for his excellent defensive leadership during the sieges of Namur and Lille, next to his conduct during the Battle of Malplaquet.

Marshal of France is a French military distinction, rather than a military rank, that is awarded to generals for exceptional achievements. The title has been awarded since 1185, though briefly abolished (1793–1804) and for a period dormant (1870–1916). It was one of the Great Officers of the Crown of France during the Ancien Régime and Bourbon Restoration, and one of the Grand Dignitaries of the Empire during the First French Empire.
