The Nieuport-Delage NiD 640 was a French four-passenger transport monoplane built by Nieuport-Delage as a smaller version of the earlier NiD 540.


The NiD 640 was an all-wood high-wing cantilever monoplane powered by a nose-mounted radial engine. An enclosed cockpit for two-crew forward of the wing and a cabin for four passengers was aft. The NiD 640 was powered by 220hp (164kW) Wright J-5C radial engine and was followed by 12 production aircraft designated NiD 641 powered by a 240hp (179kW) Lorraine 7M Mizar radial engine. The NiD 640 was converted to an ambulance aircraft and later had a Mizar engine fitted to bring it up to 641 standard. One aircraft was powered by an Armstrong Siddeley Lynx Major engine and designated the NiD 642 but it did not find a buyer and was scrapped. Seven Ni-D 641 aircraft were flown by Société des Transports Aériens Rapides (STAR), a subsidiary of Nieport-Delage, on cargo and passenger services from Paris.
