Tour Areva (previously known as Tour Framatome and Tour Fiat) is an office skyscraper 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 184 m (604 feet) tall. It is the second-tallest skyscraper in La Défense and the third-tallest skyscraper in Île-de-France. Tour Areva is entirely black; its cladding is made of dark granite and darkened window. 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 movie " 2001: A Space Odyssey".

A twin tower of Tour Areva was initially planned at the current location of the Tour Total, but was cancelled due to the oil crisis of 1974.
