Marie de Rohan (Marie Aimée; December 1600 – 12 August 1679) was a French aristocrat, famed for being the center of many of the intrigues of the first half of the 17th century in France. In various sources, she is often known simply as Madame de Chevreuse.

Marie de Rohan, styled Mademoiselle de Montbazon, was the daughter of Hercule de Rohan, Duke of Montbazon and head of the House of Rohan, possessed of great estates in Brittany and Anjou, enjoying princely rank at the French court. Her mother was Madeleine de Lenoncourt.

In September 1617, she married the Grand Constable (supreme commander of the French armies) Charles d'Albert, Duke of Luynes, a favourite of King Louis XIII. He formed her taste for unscrupulous political intrigue, introducing her at court, where she gained the confidence of both the king and queen. In December 1618, Louis XIII named her surintendante of the queen's household, ousting the Connétable de Montmorency. Her influence with the queen consort, Anne of Austria, was unrivaled.

In 1620, she gave birth to Louis Charles d'Albert, for whom Louis XIII stood godfather. Louis-Charles became the second Duke of Luynes and married his mother's sister, Anne de Rohan. His daughter Jeanne Baptiste, simultaneously Marie's granddaughter and niece, was the mistress of Victor Amadeus II of Sardinia and ancestress of the Savoy kings of Italy.
