Daulon was a French automotive brand that emerged in the early 1950s. The company was known for its unique design, particularly a cigar-shaped single-seater three-wheeler. This vehicle was developed by M. Daulon in collaboration with the coachbuilder Gordia.

The Daulon prototype was initially powered by a Villiers 250cc single-cylinder two-stroke engine, which was later upgraded to a JAP 350cc engine. Despite its innovative design and engineering, the Daulon vehicle remained a prototype and did not enter mass production. The brand's brief existence highlighted the experimental nature of automotive design during that era in France.
