Louis de Conflans, marquis d'Armentières (23 February 1711 – 18 January 1774) was a French general.
According to Saint-Simon's memoirs, Louis's branch of the family had fallen on hard times, but rose back into the upper circles of the court via Louis's father's and uncles's marriage to two daughters of Claude de Jussac, captain of the 'gardes de Monsieur', the regiment guarding the king's younger brother.
On 19 September 1734, he fought at Guastalla under the maréchal de Coigny and was wounded in the neck by a musket shot.
He served in the Bohemian expedition during the first phase of the War of the Austrian Succession, under maréchal de Belle-Isle.
He fought at Rocourt on 11 October 1746 and brought Louis XV news of the victory.
