Ireland in the Eurovision Song Contest 2009

Ireland participated in the Eurovision Song Contest 2009 with the song "Et Cetera" written by Niall Mooney, Jonas Gladnikoff, Daniele Moretti and Christina Schilling. The song was performed by Sinéad Mulvey and the band Black Daisy. The Irish broadcaster Raidió Teilifís Éireann (RTÉ) organised the national final Eurosong 2009 in order to select the Irish entry for the 2009 contest in Moscow, Russia. Six songs faced the votes of four regional juries and a public televote, ultimately resulting in the selection of "Et Cetera" performed by Sinéad Mulvey and Black Daisy as the Irish Eurovision entry.

Ireland was drawn to compete in the second semi-final of the Eurovision Song Contest which took place on 14 May 2009. Performing during the show in position 2, "Et Cetera" was not announced among the top 10 entries of the second semi-final and therefore did not qualify to compete in the final. It was later revealed that Ireland placed eleventh out of the 19 participating countries in the semi-final with 52 points.
