Louise Diane d'Orléans (27 June 1716 – 26 September 1736) was Princess of Conti from her marriage to Prince Louis François in 1732, until her death in childbirth.

[2] The style of Mademoiselle de Chartres had been used by her elder sister Adélaïde, who, by the time of Louise Diane's birth, was a nun at Chelles.

The Palais-Royal was where the régent held his court and lived openly with his mistress Marie Thérèse de Parabère.

Upon the death of her father in 1723, at Versailles, at the age of forty-nine, her only brother inherited the title of Duke of Orléans and, in 1724, he married Margravine Johanna of Baden-Baden.

In December 1731, it was decided that she should marry her cousin Louis François de Bourbon, Prince of Conti.

[2] Her marriage was arranged by her mother Françoise Marie and her first cousin (and subsequent mother-in-law) Louise Élisabeth, Dowager Princess of Conti.
