Belgium in the Eurovision Song Contest 2018

Belgium was represented at the Eurovision Song Contest 2018 with the song "A Matter of Time", written by Laura Groeseneken, Alex Callier, and Maxime Tribeche, and performed by Groeseneken herself under her stage name Sennek. The Belgian participating broadcaster, Flemish Vlaamse Radio- en Televisieomroeporganisatie (VRT), internally selected its entry for the contest. The artist was announced on 28 September 2017, and the song was presented to the public on 5 March 2018.

Belgium was drawn to compete in the first semi-final of the Eurovision Song Contest which took place on 8 May 2018. Performing during the show in position 4, "A Matter of Time" was not announced among the top 10 entries of the first semi-final and therefore did not qualify to compete in the final. It was later revealed that Belgium placed twelfth out of the 19 participating countries in the semi-final with 91 points.
