Le Flagey is a cultural institution located in the former headquarters of the Belgian National Institute of Radio Broadcasting (formerly known as the Maison de la Radio) on Eugène Flagey Square, in Ixelles (Brussels). The building , designed by Joseph Diongre, was completed in 1938 in Streamline Moderne (an international style of Art Deco). It owes its name to Eugène Flagey, a Belgian lawyer and politician. When the broadcaster left in 1974, the building was refurbished as a cultural community centre.

Le Flagey has now regained its original function by creating a musical space with recording studios and concerts venues. It has become a place with an eclectic programme. Its Studio 4 is one of the concert halls with the best acoustics worldwide, home to the Brussels Philharmonic. It is also used as a recording studio; the award-winning soundtrack of the movie The Artist was recorded there.

This cultural centre has a room permanently dedicated to cinema. It screens films programmed by the Cinémathèque royale de Belgique; either indisputable classics or recent curiosities that have not been distributed in the commercial network. Exceptional screenings are sometimes organised in the prestigious concert hall, the largest in Brussels, where a huge screen is installed for the event.
