Charles Auguste Émile Durand, known as Carolus-Duran (Lille 4 July 1837 - 17 February 1917 Paris), was a French painter and art instructor. He is noted for his stylish depictions of members of high society in Third Republic France.
Carolus-Duran studied at the Lille Academy and then at the Académie des Beaux-Arts in Paris.
In 1861, he traveled to Italy and Spain for further study, especially devoting himself to the pictures of Velázquez.
His dramatic painting Murdered, or The Assassination (1866), was one of his first successes, and is now in the Lille museum.
