Louis Charles Alphonse Léodgard d'Orléans, Count of Beaujolais (17 October 1779 – 30 May 1808) was a French prince of the blood, son of Philippe Égalité and the younger brother of King Louis-Philippe I of the French.

Louis Charles was born at the Palais-Royal in Paris. He was the third and youngest son of Philippe d'Orléans, Duke of Chartres, later Duke of Orléans as Philippe Égalité, and of his wife, Louise Marie Adélaïde de Bourbon. As a member of the reigning House of Bourbon, he was a prince du sang.

His mother was the greatest heiress of the age as the only surviving child of the vastly wealthy duc de Penthièvre. She was also the sister in law of the famous princesse de Lamballe.

In 1781 the Countess of Genlis was appointed to be the governess to Louis-Charles and to his two older brothers Louis-Philippe and Antoine. Two years later the abbé Mariottini, nephew of the apostolic nuncio to France was made his tutor, but he resigned in 1786 after a conflict with Madame de Genlis. Louis Charles was then tutored by the first chamberlain Barrois, before being assigned to the under-governor Lebrun in 1789.

In April 1793 Louis Charles was arrested with his father and imprisoned at Fort-Saint-Jean in Marseille. During his imprisonment he contracted tuberculosis, a condition which eventually caused his death. His father was executed in November 1793 but Louis Charles remained imprisoned until August 1796 when the Directory decided to exile him and his brother Antoine to Philadelphia. The French chargé d'affaires in Philadelphia settled upon Louis-Charles an annual pension of 15,000 francs.
