Belgium in the Eurovision Song Contest 2024

Belgium participated in the Eurovision Song Contest 2024 in Malmö, Sweden, with "Before the Party's Over" performed by Mustii. The Walloon broadcaster Radio Télévision Belge de la Communauté Française (RTBF) internally selected the Belgian entrant for the contest.

Background
Prior to the 2024 contest, Belgium had participated in the Eurovision Song Contest sixty-four times since its debut as one of seven countries to take part in, only missing the , and  editions. Since then, the country has won the contest on one occasion in with the song "J'aime la vie", performed by Sandra Kim. Following the introduction of semi-finals for, Belgium had featured in nine finals. In, Gustaph represented the nation with the song "Because of You", qualifying for the final and ultimately placing 7th.

The Belgian participation in the contest alternates between two broadcasters: the Flemish Vlaamse Radio- en Televisieomroeporganisatie (VRT) and the Walloon Radio Télévision Belge de la Communauté Française (RTBF). Both broadcasters had selected the Belgian entry using national finals and internal selections in the past. For the 2024 contest, RTBF was responsible for organising the selection process for the Belgian entry. On 16 August 2023, the broadcaster confirmed its intention to participate in the event, opting for an internal selection.

Internal selection
On 30 August 2023, RTBF announced they had internally selected Mustii as the Belgian entrant for the Eurovision Song Contest 2024. His entry was selected later, with RTBF calling for interested people to register on a dedicated website between 11 and 17 January 2024 in order to record a repeated line, which was intended to be included as a choir in the final version of the song;  at the closing of the window, over 1,000 people had recorded the line, mostly from abroad. The entry, titled "Before the Party's Over", officially premiered on 20 February 2024 on the radio programme Le 8/9 on VivaCité; however, it was accidentally played in its entirety on Tipik two days prior.

Promotion
As part of the promotion of his participation in the contest, Mustii attended the PrePartyES in Madrid on 30 March 2024, the Barcelona Eurovision Party on 6 April 2024, the London Eurovision Party on 7 April 2024, the Eurovision in Concert event in Amsterdam on 13 April 2024, and the Nordic Eurovision Party in Stockholm on 14 April 2024. In addition, he performed at the Eurovision Village in Malmö on 4 May 2024.

Calls for exclusion of Israel
The inclusion of in the list of participants for the Eurovision Song Contest 2024 despite the ongoing humanitarian crisis resulting from Israeli military operations in the Gaza Strip during the Israel–Hamas war sparked controversy in Belgium as well as several other participating countries, with several groups and politicians in the country calling for the removal of Israel from the contest, including the Walloon and Flemish ministers of media Bénédicte Linard and Benjamin Dalle. The start of VRT's broadcast of the second semi-final, where Israel was set to compete, was disrupted by a message aired by the broadcaster's internal trade union which called out Israel's human rights violations and alleged destruction of the freedom of press amid the war.

At Eurovision
The Eurovision Song Contest 2024 took place at the Malmö Arena in Malmö, Sweden, and consisted of two semi-finals held on the respective dates of 7 and 9 May and the final on 11 May 2024. All nations with the exceptions of the host country and the "Big Five" (France, Germany, Italy, Spain and the United Kingdom) were required to qualify from one of two semi-finals in order to compete in the final; the top ten countries from each semi-final progressed to the final. On 30 January 2024, an allocation draw was held to determine which of the two semi-finals, as well as which half of the show, each country would perform in; the European Broadcasting Union (EBU) split up the competing countries into different pots based on voting patterns from previous contests, with countries with favourable voting histories put into the same pot. Belgium was scheduled for the second half of the second semi-final. The shows' producers then decided the running order for the semi-finals; Belgium was set to perform in position 12.

In Wallonia, RTBF broadcast the first semi-final on Tipik and the second semi-final and the final on La Une, as well as all shows on its streaming platform Auvio and the final on radio via VivaCité,  with commentary by Maureen Louys and Jean-Louis Lahaye. In Flanders, VRT is broadcasting all shows on VRT 1 as well as on its streaming platform VRT MAX, and the final on Radio 2, with commentary by Peter Van de Veire; Van de Veire is also hosting the pre-show Hello Malmö on VRT 1. In addition, as part of the Eurovision programming, VRT broadcast the Het Grote Songfestivalfeest concert on 27 April and 4 May; a documentary titled ABBA – Against the Odds on 28 April and 5 May, which it cooperated to produce with DR and SVT alongside other EBU member broadcasters – namely ARD/WDR, the BBC, ČT, ERR, France Télévisions, NRK, NTR, RÚV and Yle – on the occasion of the 50th anniversary of with "Waterloo" by ABBA; and the documentary Mustii, de weg naar Malmö on 8 May, dedicated to Mustii's Eurovision journey; a number of other Eurovision-themed programmes are airing during the week on VRT 1, Radio 2 and MNM.
