The union of public broadcasters of Serbia and Montenegro, Udruženje javnih radija i televizija (UJRT), confirmed its intentions to debut at the Eurovision Song Contest in its 2004 edition after an application was submitted to take part in 2003 but was rejected due to late changes to the relegation procedure.

Evropesma-Europjesma 2004 was the national final organised by UJRT in order to select the Serbian–Monetengrin entry for the Eurovision Song Contest 2004.

The competition took place at the Sava Centar in Belgrade on 21 February 2004, hosted by Aleksandar Bojović and Nina Mudrinić.

The winner, "Lane moje" performed by Željko Joksimović, was decided by a combination of votes from a jury panel (8/9) and the Serbia and Montenegro public via televoting (1/9).

According to the rules, all nations with the exceptions of the host country, the "Big Four" (France, Germany, Spain and the United Kingdom) and the ten highest placed finishers in the 2003 contest are required to qualify from the semi-final on 12 May 2004 in order to compete for the final on 15 May 2004; the top ten countries from the semi-final progress to the final.
