Bosnia and Herzegovina in the Eurovision Song Contest 2004

Bosnia and Herzegovina was represented at the Eurovision Song Contest 2004 with the song "In the Disco", written by Vesna Pisarović, and performed by Deen. The Bosnian-Herzegovinian participating broadcaster, Public Broadcasting Service of Bosnia and Herzegovina (PBSBiH), organised the national final BH Eurosong 2004 in order to select its entry for contest, after having previously selected the performer internally. On 15 January 2004, the broadcaster revealed that they had internally selected Deen as its representative. Five songs participated during the song selection show on 6 March 2004 where a combination of an eleven-member jury and public televoting selected "In the Disco" as the winning song. Songwriter Vesna Pisarović had represented Croatia in 2002 with the song "Everything I Want".

Bosnia and Herzegovina competed in the semi-final of the Eurovision Song Contest which took place on 12 May 2004. Performing during the show in position 21, "In the Disco" was announced among the top 10 entries of the semi-final and therefore qualified to compete in the final on 14 May. It was later revealed that Bosnia and Herzegovina placed seventh out of the 22 participating countries in the semi-final with 133 points. In the final, Bosnia and Herzegovina performed in position 12 and placed ninth out of the 24 participating countries, scoring 91 points.
