The Caudron C.280 Phalène ("Moth") was a civil utility aircraft built in France during the 1930s.

It was a high-wing braced monoplane of conventional configuration with fixed tailskid undercarriage.

The structure was wooden throughout, with the forward fuselage skinned with plywood, and the rest of the aircraft fabric-covered.

The type proved popular on the civil market, with a number of long-distance flights staged to promote it.

The French military also purchased a number of examples under the C.400 and C.410 designations.
