Charles Camille Heidsieck (1822–1893) was a French Champagne merchant who founded the Champagne firm Charles Heidsieck in 1851. He is credited with popularizing Champagne in the United States and was known as "Champagne Charlie" during his stay.
During the American Civil War Heidsieck was imprisoned under suspicion of being a spy for the French government and the Confederacy. His imprisonment sparked an international incident between France and US over what became known as The Heidsieck Incident.
