Brussels by Night is a Belgian drama film from 1983, directed by former Humo journalist Marc Didden. The low budget picture was financed partly by Herman Schueremans, organizer of the Flemish rock festival Rock Werchter. The film was named after a 1979 song by Raymond van het Groenewoud, who also wrote the soundtrack for the movie.

Brussels by Night was important in Belgian film history because its bleak, grey atmosphere and stream of consciousness structure were a sharp contrast with the more conventional films the country produced up to then.
