Dowen was a French automobile manufacturer that emerged around 1906, associated with Barret Freres, a company based in Lyons. The details surrounding Dowen's production are sparse, with the primary evidence of its existence being an advertisement that depicted a conventional front-engined side-entrance tourer.

The Etablissements Dowen were reported to have engaged in the manufacturing of cars, motorcycles, and bicycles. However, it remains unclear whether Barret Freres acted as agents for Dowen or if they were involved in the manufacturing process. The limited information available suggests that Dowen's presence in the automotive industry was brief and not extensively documented.
