Luxembourg made its debut in the Eurovision Song Contest in 1956 and has since participated thirty-nine times, showcasing its rich musical talent. The country's national broadcaster, RTL Lëtzebuerg, has been the driving force behind its representation. Notably, Luxembourg participated in every contest from 1956 until 1993, with the exception of the 1959 event.
With five victories to its name, Luxembourg stands as one of the most successful nations in Eurovision history. The country clinched its first win in 1961 with "Nous les amoureux" by Jean-Claude Pascal, followed by another triumph in 1965 with France Gall's "Poupée de cire, poupée de son." Luxembourg achieved back-to-back wins in 1972 and 1973, thanks to Vicky Leandros and Anne-Marie David, and secured its last victory in 1983 with Corinne Hermès's "Si la vie est cadeau."
Throughout its Eurovision journey, Luxembourg has also recorded two third-place finishes in 1962 and 1986, and has placed within the top five thirteen times and the top ten nineteen times. However, the nation's fortunes took a downturn in the late 1980s and early 1990s, culminating in a relegation after finishing among the bottom seven in 1993.
After a long hiatus of thirty-one years, Luxembourg returned to the contest in 2024, successfully qualifying from the semi-finals and finishing in thirteenth place in the final. The following year, in 2025, the country again qualified for the final, placing twenty-second.
