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. The song was performed by Sennek, which is the artistic name of singer Laura Groeseneken who was internally selected by the Flemish broadcaster Vlaamse Radio- en Televisieomroeporganisatie (VRT) in September 2017 to represent the nation at the 2018 contest in Lisbon, Portugal. The song, "A Matter of Time", 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.
