Armenia participated in the Eurovision Song Contest 2011 in Düsseldorf, Germany and was represented by Emmy who was selected through an internal selection and their song through a televised national final, organised by the Armenian broadcaster Public Television of Armenia (ARMTV).

On 11 December, ARMTV announced at a press conference that Emmy would represent Armenia in Düsseldorf. Just like in 2008, a public call for songs was opened in order to hold a televised song selection. Apart from complying with the regulations set by the European Broadcasting Union, all submissions in Armenia must be written in either Armenian or English.

A jury finally selected four songs, which were to be sung in a national final on 19 February. The national final was later moved to a different date - 26 February, however this date was moved forward as well because of a personal tragedy in Emmy's family. Finally, the Armenian national selection was scheduled to take place on 5 March. The winning song was chosen via televoting and a jury, and each were accountable for 50% of the votes.

On 10 February, ARMTV announced the names of the composers: DerHova, Apricota, Vahram Petrosyan, Martin Kesici. No further details such as the songs titles or lyrics were released at the time. From 2 March, the four songs were occasionally played on radio, posted in internet and broadcast on TV to give voters time to make up their minds by the final.

The Armenian entry for the 2011 Eurovision Song Contest was picked out of four songs, all of which were performed by Emmy - who had already been internally chosen to represent Armenia in December. A 50/50 combination of televoting and the votes of an expert jury decided that she should sing "Boom Boom" in Düsseldorf. Boom Boom, a cheerful up-tempo pop song, was selected for the contest. The song was written by the members of the band Apricota, Hayk Harutyunyan and Hayk Hovhannisyan, with the lyrics by Sosi Khanikyan.

Armenia competed fourth in the first semi-final on 10 May. The country did not qualify to the final for the first time since it joined Eurovision. However its entry came very close to qualifying after coming twelfth place in the semi-final. It received a total of 54 points, just one point behind tenth place, Switzerland.
