Citroën (French pronunciation: ​[si.tʁɔ.ˈɛn]) is a major French automobile manufacturer, part of the PSA Peugeot Citroën group since 1976. Founded in 1919 by French industrialist André-Gustave Citroën (1878–1935).

In 1934, Citroën secured its reputation for innovation with the Traction Avant, not only the world's first mass-produced front-wheel drive car, but also one of the first cars to feature a unitary-type body, with no chassis frame holding the mechanical components.
