Louise Charlotte de Noailles, Duchess of Duras (23 August 1745-12 February 1832), was a French courtier and memoirist.

In 1767, de Duras was appointed lady in waiting, Dame du Palais, to queen Marie Leszczynska to whom her mother served as chief lady-in-waiting.

In 1770 she was, as her mother and many of the members of the household of the late queen, appointed to serve Marie Antoinette upon her arrival to France.

However, the queen also felt respect for her, and it was therefore often Duras who was selected to correct the queen whenever she made a mistake, such as when Marie Antoinette wished to visit the theater just one day after the death of her close friend Thérèse-Lucy de Dillon, which gave her much bad publicity.

She herself remained in prison and was liberated after the fall of Robespierre, settling with her mother-in-law, Louise Françoise de Coëtquen (1724-1802).
