Switzerland in the Eurovision Song Contest 2004

Switzerland was represented at the Eurovision Song Contest 2004 with the song "Celebrate", written by Greg Manning, and performed by Piero Esteriore and the MusicStars. The Swiss participating broadcaster, the Swiss Broadcasting Corporation (SRG SSR), selected its entry through the national final Eurosong 2004. The broadcaster returned to the contest after a one-year absence following its relegation from 2003 as one of the bottom five entrants in 2002. The Swiss-German/Romansh broadcaster Schweizer Fernsehen der deutschen und rätoromanischen Schweiz (SF DRS), the Swiss-French broadcaster Télévision Suisse Romande (TSR), and the Swiss-Italian broadcaster Televisione svizzera di lingua italiana (TSI) each conducted varying selections and a total of twelve entries were selected to advance to the televised national final—four artists and songs from each selection. The twelve finalists performed during the national final on 6 March 2004 where two rounds of regional televoting ultimately selected "Celebrate" performed by Piero Esteriore and the MusicStars as the winner.

Switzerland competed in the semi-final of the Eurovision Song Contest which took place on 12 May 2004. Performing during the show in position 3, "Celebrate" was not announced among the top 10 entries of the semi-final and therefore did not qualify to compete in the final. It was later revealed that Switzerland placed twenty-second (last) out of the 22 participating countries in the semi-final and failed to score any points. This marked the fourth time the nation had received nul points in the history of the competition.
