The Peugeot 402 is a large family car produced in Sochaux, France from 1935 to 1942 by Peugeot. It was unveiled at the Paris Motor Show in 1935, replacing the Peugeot 401.

Émile Darl'mat (1892–1970) was the creator and owner of a Peugeot distributor with a car body business established at the rue de l'Université in Paris in 1923. In the 1930s the firm gained prominence as a low volume manufacturer of Peugeot-based sports cars. Business was interrupted by the Second World War, but at least one prototype was kept hidden throughout the period and directly after the war Darl'mat returned to the construction of special bodied Peugeots, although in the impoverished condition of post-war France business never returned to the volumes achieved during the 1930s.
