The Belgian participating broadcaster, Flemish Belgische Radio- en Televisieomroep (BRT), selected its entry through a national final.

The 1983 national final has gone down as the most controversial in Belgian Eurovision history due to the extreme hostility shown by the audience towards Pas de Deux's victory.

Each show had live music from the BRT Big Band conducted by Freddy Sunder, and each artist had the option to use backing vocals provided by Bob Baelemans, Fred Beekmans, Luc Smets, and Linda Williams.

The jury was chaired by Tania Humblet and consisted of: Rita Goossens, Claude Blondeel, Paul De Wijngaart, Jan Schoukens, Johannes Thuy, Roel Van Bambost, Mike Verdrengh, and Zaki.

Many walked out in disgust before the end of the transmission and Pas de Deux (who seemed to find the audience reaction amusing rather than upsetting) reprised their winning song to a half-empty house, having to compete against a chorus of jeers and booing.
