Louis Charles d'Albert, 2nd Duke of Luynes (25 December 1620 – 10 October 1690), was a French nobleman and peer of France. He was a translator and moralist who was the first translator of the work of René Descartes.

Louis-Charles d'Albert was born 25 December 1620 in the Louvre. He was a son of Charles d'Albert, 1st Duke of Luynes, a favorite of Louis XIII, and Princess Marie Aimée de Rohan, Mademoiselle de Montbazon (1600–1679). After his father's death, his mother remarried to Claude of Lorraine, Duke of Chevreuse (a son of Henry I, Duke of Guise), with whom she had three daughters. Upon Claude's death in 1655, the Chevreuse peerage became extinct and his mother bought the duchy. After her death in August 1679, Louis Charles inherited the duchy of Chevreuse, and his descendants have held it since.^[1]

His maternal grandparents were Hercules de Rohan, Duke of Montbazon and, his first wife, Marie de Bretagne d'Avaugour.
