Charles d'Orléans (Charles Ferdinand Louis Philippe Emmanuel; 1 January 1820 – 25 July 1828) was the eighth child of the Duke and Duchess of Orléans, future Louis Philippe I and la Reine Marie Amélie. He was created Duke of Penthièvre, a title previously held by his great grandfather.

Charles d'Orléans was born at the Palais Royal in Paris, the official city residence of the Orléans family since 1692. Inside his family, he was nicknamed Pimpin.

He was the fourth of six sons born to the Orléans; Ferdinand Philippe born in 1810; the Duke of Nemours born in 1814; the Prince of Joinville born in 1818 who was followed by Charles. His younger brother's were the Duke of Aumale and the Duke of Montpensier. His oldest sister Louise married Leopold I of Belgium. Another sister Clémentine was the mother of Ferdinand I of Bulgaria. He was born one month premature and it was believed he would not live. Although he lived, he remained both physically weak and mentally retarded. He was cared by a servant named Joseph Uginet, who loved him greatly.

Charles was given the title of Duke of Penthièvre, which had passed to the House of Orléans by inheritance; Charles paternal grandmother Louise Marie Adélaïde de Bourbon, wife of Philippe Égalité, was a great heiress and inherited the Penthièvre fortune from her father prior to the Revolution. As such, the Orléans family were one of the wealthiest in Europe rivalling that of the mainline in the previous century.
