Belgium in the Eurovision Song Contest 1990
Belgium was represented by Philippe Lafontaine, with the song "Macédomienne", at the 1990 Eurovision Song Contest, which took place in Zagreb on 5 May.  Lafontaine was chosen internally by broadcaster RTBF to be that year's Belgian representative.

Internal selection 
On the unusually early date of 8 January, Lafontaine's self-penned song "Macédomienne" was presented as the Belgian entry by broadcaster André Vermeulen in a segment of RTBF's evening news programme.  The song was dedicated to Lafontaine's Macedonian wife, and Lafontaine refused to allow the commercial release of the track, going so far as destroying the original master tape to prevent it being copied.  "Macédomienne" remains one of very few Eurovision entries which was never released commercially even in its own country.

At Eurovision 
On the night of the final Lafontaine performed 3rd in the running order, following Greece and preceding Turkey.  At the close of the voting "Macédomienne" had received 46 points from ten countries (the highest being 8 from France and Germany), placing Belgium 12th out of 22 entries.  The Belgian jury awarded its 12 points to the United Kingdom.
