Tour Areva (previously known as Tour Framatome and Tour Fiat) is an office skyscraper designed by global architects SOM and located in La Défense, a high-rise business district, and in the commune of Courbevoie, France, west of Paris.

Built in 1974, the tower is 178 m (584 ft) tall.

Tour Areva is entirely black; its cladding is made of dark granite and darkened windows. Its shape is that of a perfect square prism. It is said that its architects were inspired by the black monolith in Stanley Kubrick's film 2001: A Space Odyssey. ^{[citation needed]}
