Belgium was present at the Eurovision Song Contest 1986, held in Bergen, Norway.
The Belgian national final to select their entry, Eurovision '86, was held on 2 March at the RTBF-TV Studios in Brussels, and was hosted by Patrick Duhamel. The winning song was decided by the following formula: 50% of the final tabulation would come from 12 "music experts" and 50% would come from 500 random Belgians polled to make up a fair segment of the Belgian population.
For 1986 (like in other even-numbered years), the Walloon broadcaster in Belgium, Radio télévision belge de la communauté française (RTBF), took responsibility for Eurovision song selection. As a result, all of the competing songs for 1986 were sung in French.
Sandra Kim performed thirteenth on the night of the Contest, following Ireland and preceding Germany. At the close of the voting the song had received 176 points, placing 1st in a field of 20 competing countries. It was the first win for Belgium in the Contest, something they have not been able to replicate since.
