Belgium was represented at the Eurovision Song Contest 1956 with two songs: "Messieurs les noyés de la Seine", composed by Jean Miret and Jack Say, with lyrics by Robert Montal, and performed by Fud Leclerc; and "Le Plus Beau Jour de ma vie", composed by Claude Alix, with lyrics by David Bée, and performed by Mony Marc.

Held on 15 April 1956, the national final saw ten songs compete to be the Belgian entries; the results were determined by the jury panel and postcard voting.
