  Until her marriage, she was known as Mademoiselle de Chartres . known as Mademoiselle de Chartres. She grew up with her younger sister Élisabeth with a convent education. Her sister would later become the Queen of Spain. 
  Louise grew up in an era when her father, known as Philippe d'Orléans or simply le Régent was the ruler of France, him being in charge of the affairs of state since the death of Louis XIV. The Palais-Royal was where the Régent held his court and lived openly with his mistress.
  In her youth, she was said to have been a very sensitive child and would grow up to be one of the more beautiful of the Regent's daughters. Despite her being another girl, (1 of 7 overall), her birth was not really greeted with the joy that had met her brother, Louis d'Orléans, Duke of Orléans.
  In December 1731, it was decided that she should marry her distant cousin Louis François de Bourbon, Prince of Conti. Her marriage was arranged by her mother Françoise Marie, Dowager Duchess of Orléans and her first cousin (and subsequent mother in law) Louise Élisabeth, Dowager Princess of Conti.
  She was baptised on 19 January 1732 by the Cardinal of Rohan and she married the Prince of Conti three days later, on 22 January. The marriage ceremony took place at the Palace of Versailles. Louise was then fifteen years old. At her wedding, her cousin Élisabeth Alexandrine de Bourbon held her train.
  After the marriage, she became known at court as Her Serene Highness, the Princess of Conti. Her husband had succeeded to the Conti title in 1727 upon the death of his father, Louis Armand II, Prince of Conti. In 1734, Louise gave birth to a son, heir to the Conti name, and, in 1736, to a second child who died at birth.
  Louise died in childbirth on 26 September 1736 outside Paris. She was buried at the Saint-André-des-Arcs church. Her only surviving son, Louis François Joseph, was the last Prince of Conti.
