Armenia in the Eurovision Song Contest 2011

Armenia was represented at the Eurovision Song Contest 2011 with the song "Boom Boom" written by Hayk Hovhannisyan, Hayk Harutyunyan and Sosi Khanikyan. The song was performed by Emmy, who was selected internally by the Armenian broadcaster Public Television of Armenia (AMPTV) to represent Armenia in the 2011 contest in Düsseldorf, Germany. Emmy's selection as the Armenian artist was announced on 11 December 2010, while the song was selected through a national final, which took place on 5 March 2011 where four songs competed. "Boom Boom" was selected as the winning song following the combination of votes from a professional jury and a public televote.

Armenia was drawn to compete in the first semi-final of the Eurovision Song Contest which took place on 10 May 2011. Performing during the show in position 4, "Boom Boom" was not announced among the top 10 entries of the first semi-final and therefore did not qualify to compete in the final. This marked the first time that Armenia failed to qualify to the final of the Eurovision Song Contest from a semi-final since its first entry in 2006. It was later revealed that Armenia placed twelfth out of the 19 participating countries in the semi-final with 54 points.
