The Caudron C.640 Typhon was a 1930s French high-speed single-seat monoplane utility aircraft built by Caudron-Renault.

The Société des Avions Caudron was a French aircraft company founded in 1909 as the Association Aéroplanes Caudron Frères by brothers Gaston and René Caudron. It was one of the earliest aircraft manufacturers in France and produced planes for the military in both World War I and World War II. From 1933 onwards, it was a subsidiary of Renault.
