Delage is a French luxury automobile and racecar company founded in 1905 by Louis Delâge in Levallois-Perret near Paris; it was acquired by Delahaye in 1935 and ceased operation in 1953.

Levallois-Perret is a commune in the Hauts-de-Seine department and Île-de-France region of north-central France. It lies on the right bank of the Seine, some 6 km (3.7 mi) from the centre of Paris in the north-western suburbs of the French capital. It is the most densely populated town in Europe and, together with neighbouring Neuilly-sur-Seine, one of the most expensive suburbs of Paris.
