Chapuis-Dornier was a French manufacturer that emerged around the year 1920, primarily recognized for producing proprietary engines. The company gained some notoriety in automotive circles, as it was occasionally listed as a manufacturer of complete automobiles. However, this classification was often based on second-hand examples that appeared in various magazines.

Despite the listings, there is no substantial published evidence to confirm that Chapuis-Dornier produced complete cars. It is more likely that the vehicles attributed to the brand were actually other manufacturers that utilized Chapuis-Dornier engines. As a result, the legacy of Chapuis-Dornier remains primarily tied to its engine production rather than a significant portfolio of complete automobiles.
