The Peugeot 504 is a mid-size, front-engine, rear-wheel-drive automobile manufactured and marketed by Peugeot from 1968 to 1983 over a single generation, primarily in four-door sedan and wagon configurations – but also as twin two-door coupé and cabriolet configurations as well as pickup truck variants.

Peugeot is a French brand of automobiles owned by Stellantis. The family business that preceded the current Peugeot companies was founded in 1810, and it is regarded as the oldest car company in the world. On 20 November 1858, Émile Peugeot applied for the lion trademark. Armand Peugeot (1849–1915) built the company's first car steam tricycle. They joined forces with Léon Serpollet in 1886; this was followed in 1890 by an internal combustion car with a Panhard-Daimler engine.
