[1] Luxembourg was drawn to compete in the first semi-final of the Eurovision Song Contest which took place on 7 May 2024 and was later selected to perform in position 15.

After a poor result in 1993, CLT was relegated from the 1994 contest in accordance with the new rules implemented at the time, and had since opted to be absent from the event.

[1] CEO of RTL Christophe Goossens stated the broadcaster was "delighted" to return to the Eurovision Song Contest and to select the 2024 Luxembourgish delegation.

The competition featured eight acts and took place on 27 January 2024 at the Rockhal in Esch-sur-Alzette, hosted by Désirée Nosbusch who had previously presented the 1984 edition of the Eurovision Song Contest held in Luxembourg City, Melody Funck, Raoul Roos and Loïc Juchem.

Applicants of the second category were also required to be non-professional singers and had to submit an introduction video containing a performance of a song of their choice until 16 July 2023.

[17][18] A final audition round took place between 22 and 24 November 2023 at the Rockhal where an international jury panel evaluated the shortlisted songs.

[13][19] The international jury panel consisted of Tali Eshkoli (Israeli television producer), Christer Björkman (Swedish television producer and presenter, represented Sweden at Eurovision in 1992), Jan Bors (creative content producer for Czech Television), Cesár Sampson (who represented Austria at Eurovision in 2018) and Alex Panayi (jury chairman, represented Cyprus at Eurovision in 1995 and in 2000).

[25][26] Prior to the final, the competing artists worked with vocal coaches Francesca Aaen and Susanne Georgi (represented Andorra at Eurovision in 2009) to prepare for their live performances.

[30] In addition to the performances of the competing entries, Vicky Leandros and Anne-Marie David (1972 and 1973 Eurovision winners for Luxembourg) opened the show with excerpts from their respective winning songs "Après toi" and "Tu te reconnaîtras", followed by all eight finalists performing a rendition of "Poupée de cire, poupée de son" by France Gall (1965 winning entry for Luxembourg).

The interval act during the show included performances from Schëppe Siwen [lb] as well as former Eurovision winners Katrina Leskanich (in 1997 for the United Kingdom as part of Katrina and the Waves), Charlotte Perrelli (in 1999 for Sweden), Ruslana (in 2004 for Ukraine) and Alexander Rybak (in 2009 for Norway) with their winning songs; Leandros also performed her 1967 Eurovision entry "L'amour est bleu" with Rybak.

[51] The Luxembourgish jury consisted of Vanessa Cum, Patrick Greis, Germain Leon Martin, Alfred Nicolas Medernach, and Irem Sosay.

Over the course of the contest, Luxembourg awarded its 12 points to Portugal in the first semi-final, and Switzerland (jury) and Israel (televote) in the final.

[53][54] RTL appointed Désirée Nosbusch, presenter of the 1984 contest, as its spokesperson to announce the Luxembourgish jury's votes in the final.

Each participating broadcaster assembles a five-member jury panel consisting of music industry professionals who are citizens of the country they represent.

[55] The individual rankings of each jury member as well as the nation's televoting results were released shortly after the grand final.
