Eliot Vassamillet is a Belgian singer who represented Belgium at the Eurovision Song Contest 2019 in Tel Aviv, Israel and failed to qualify for the grand final. He was selected internally with the song "Wake Up" written by Pierre Dumoulin, who previously wrote "City Lights" for singer Blanche, which placed 4th in Eurovision Song Contest 2017, and Vassamillet himself.

Belgium has participated in the Eurovision Song Contest 64 times since making its debut as one of seven countries at the first contest in 1956. The only countries with the same number or more appearances are Germany (66), France (65) and the United Kingdom (65). Belgium have been absent only three times in total, in 1994, 1997 and 2001, due to low scores in the previous contests that relegated them from the contest. Belgium has won the contest once, in 1986.
