Marie Émilie de Joly de Choin
- Born: 2 Aug 1670
- Marriage: Louis, le Grand Dauphin Bourbon of France
- Died: 1732 at age 62
Marie Émilie de Joly de Choin was a French lady-in-waiting, the lover and later the morganatic spouse of Louis, Dauphin of France. As a morganatic spouse, she was not styled the Dauphine of France.
Marie Émilie was born in Bourg-en-Bresse to Pierre de Joly de Choin and Madame d'Urre d'Aiguebonne. She was a lady-in-waiting to the king's favourite daughter, the princess de Conti. Marie Émilie was considered to be unattractive.
She entered into a relationship with Louis, le Grand dauphin, in parallel to having a relationship with the Count of Clermont. It was rumoured that Marie Émilie and Clermont planned to conquer the throne by producing a child from Louis through her. When these plans were discovered, Marie Émilie and Clermont were both exiled from court (1694).
The relationship to Louis did not end, however.
Marie Émilie married Louis secretly in 1695. Marie Émilie did not, however, acquire the title of Dauphine, and she was not received at court. Pregnant at the time of her secret marriage, she gave birth a son who was sent to the countryside and died aged two in 1697 without receiving a name. Ultimately the marriage remained childless.
Marie Émilie resided in the palace of Meudon, where she imitated the morganatic spouse of the king, Madame de Maintenton, by acting as the queen of a court and receiving dukes and foreign diplomats.
After the death of the dauphin in 1711, she withdrew into retirement. She died in 1732 in Paris, "universally respected for her private virtues".
Marie married Louis, le Grand Dauphin Bourbon of France, son of King Louis XIV "le Roi-Soleil" Bourbon of France and Maria Theresa of Spain. (Louis, le Grand Dauphin Bourbon of France was born on 1 Nov 1662, christened on 24 Mar 1668 and died on 14 Apr 1711.)
