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

The company was founded in 1905 by Louis Delage, who borrowed Fr 35,000, giving up a salary of Fr 600 a month to do so.

Its first location was on the Rue Cormeilles in Levallois-Perret. The company at first had just two lathes and three employees, one of them Peugeot's former chief designer. Delage initially produced parts for Helbé, with the De Dion-Bouton engine and chassis assembled by Helbé; Delage added only the body.

The first model was the Type A, a voiturette which appeared in 1906. It was powered by a one-cylinder De Dion-Bouton of 4.5 or 9 hp (3.4 or 6.7 kW; 4.6 or 9.1 PS).[2] Like other early carmakers, Delage participated in motor racing, entering the Coupe de Voiturettes held at Rambouillet in November 1906 with a 9 hp (6.7 kW; 9.1 PS) racer. Seven days of regularity trials decided the entrants, and one of the two 9 hp (6.7 kW; 9.1 PS) Delage specials was wrecked in the rain on the fifth; nevertheless, Ménard, the other works driver, came second in the event, behind a Sizaire-Naudin.

In 1907 the factory moved to the Rue Baudin Levallois, where a 4,000 m2 (43,000 sq ft) workshop allowed it to grow. The two-cylinder Delages were no match for the competition this year at the Coupe des Voiturettes.

In 1908, the success enabled the development of the factory and entry into more Grand Prix races. That year, racing success returned: Delage won the Grand Prix des Voiturettes held 6 July.] This event, six laps of the 47.74 mi (76.83 km) Dieppe Grand Prix circuit, saw 47 starters.[2] Delage fielded three cars: a pair with 1,242 cc (75.8 cu in) (78 by 130 mm (3.1 by 5.1 in)) De Dion-Bouton twins, driven by Thomas and Lucas-Bonnard, and a radical 28 hp (21 kW; 28 PS) 1,257 cc (76.7 cu in) (100 by 160 mm (3.9 by 6.3 in)) one-cylinder[4] (built by Nemorin Causan) in the hands of Delage dealer Albert Guyot. Guyot won at an average 49.8 mph (80.1 km/h), not needing to stop for fuel. All three Delages finished this time, Thomas the quickest of the two-cylinder cars, while the team also took home the regularity prize.[5] These good results contributed to total sales exceeding 300 cars for the year.
