The Caudron C.61 was a French three-engined civil transport biplane aircraft built by the French aeroplane manufacturer Caudron. It was constructed of wood and covered in fabric.
The prototype C.61 (F-ESAE) had a freight hold and cabin for six passengers. The conventional landing gear also included a wheel beneath the nose to prevent nose-overs on landing. For the production C.61s the cabin size was increased to accommodate eight passengers.
In 1924 many C.61s were modified to take 194 kW (260 hp) Salmson CM.9 radial engines outboard, increasing the maximum loaded weight to 4,834 kg (10,657 lb).
