Belgium in the Eurovision Song Contest

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.

In the first 20 years of the contest, Belgium's best result was Tonia's fourth place in 1966. In 1978, Jean Vallée achieved Belgium's first top three placement, when he was second. Sandra Kim became the first and to date only winner for Belgium in 1986, when she won as a 13-year-old in Bergen, performing the song "J'aime la vie". Belgium's only other top three result came in 2003, when the group Urban Trad finished second in Riga, losing out by only two points. Belgium has finished last in the contest eight times, most recently in 2000, and has twice received nul points, in 1962 and 1965.

After the introduction of the semi-finals in 2004, Belgium failed to reach the final for five consecutive years (2005–09). Since 2010, Belgium has become more successful, qualifying for the final in eight out of 13 contests and placing in the top ten five times, with Tom Dice (sixth in 2010), Loïc Nottet (fourth in 2015), Laura Tesoro (tenth in 2016), Blanche (fourth in 2017), and Gustaph (seventh in 2023).
