Luxembourg was represented at the Eurovision Song Contest 2025 with the song "La poupée monte le son", written by Christophe Houssin, Julien Salvia, and Ludovic-Alexandre Vidal, and performed by Laura Thorn. The Luxembourgish participating broadcaster, RTL Lëtzebuerg (RTL), organised the Luxembourg Song Contest 2025 in order to select its entry for the contest.

At the end of the show, "La poupée monte le son" was announced among the top 10 entries of the second semi-final and hence qualified to compete in the final, marking a second consecutive qualification for the country. It was later revealed that Luxembourg placed seventh out of the sixteen participating countries in the semi-final with 62 points. In the final, Luxembourg performed in position 2 and placed twenty-second out of the 26 participating countries, scoring a total of 47 points.
