De Bazalaire was a French automobile manufacturer established in Paris in 1908. The company was founded by F. de Bazahire and initially gained attention when its cars participated in the Coupe des Voiturettes in 1907, although production did not commence until the following year.

In its early years, De Bazalaire offered a range of models, including an 1100cc 8/9 horsepower twin-cylinder car, a 1.7-litre 12/14 horsepower twin-cylinder model, and a 2-litre four-cylinder variant. These vehicles featured L-head side-valve engines and rear-axle gearboxes. Additionally, a smaller six-cylinder model was marketed under the name Busson-Bazalaire.

By 1910, the company adopted overhead inlet valves and introduced a larger 2.5-litre six-cylinder model. In 1913, De Bazalaire experimented with the Fischer side-valve engine, although it did not enter production. Instead, the company produced a lineup of five four-cylinder cars that utilized Ballot engines in the smaller models and Janvier engines in the larger ones. Notably, the Type MM-Sport was equipped with a long-stroke 3.6-litre T-head engine.

Following World War I, De Bazalaire continued to manufacture conventional cars, primarily using single overhead cam S.C.A.P. engines with a displacement of 1690cc. The 3.6-litre Janvier model remained in production until 1924, marking the end of the company's automotive endeavors. De Bazalaire ceased operations in 1928, concluding its brief but notable presence in the automotive industry.
