Charles de Lorraine, 4th Duke of Guise (2 August 1571 – 30 September 1640) was the son of Henry I, Duke of Guise and Catherine of Cleves.
He was born in Joinville, (Haute-Marne department), in the Champagne-Ardenne region of northeastern France. Originally styled the Chevalier de Guise, he succeeded as Duke of Chevreuse upon the death of his great-uncle Charles of Guise, Cardinal of Lorraine, a title he later resigned to his brother Claude.
After his father's assassination in 1588, he succeeded him as Duke of Guise, but was kept in prison in Tours for three years, escaping in 1591. While the Catholic League had great hopes for him, and considered placing him on the throne, he declared his support for Henry IV of France in 1594, for which Henry paid him four million livres and made him Governor of Provence. In 1595, he captured Marseille from the Duc d'Épernon, who held it for the League.
He was later created Grand Master of France and Admiral of the Levant.
Falling into disfavor with Cardinal Richelieu for siding with Marie de' Medici, he withdrew to Italy in 1631. His wife and younger children joined him in Florence, where the family was protected by the House of Medici. His sons François and Charles Louis died in Italy during these years of exile. Duke Charles himself died, at Cuneo, in 1640. His widow and children (among them Marie, "Mademoiselle de Guise" were permitted to return to France in 1643.
