The twelve qualifiers competed in the final which resulted in "Kruna" performed by Nevena Božović as the winner following the combination of votes from a five-member jury panel and a public televote.

Performing during the show in position 9, "Kruna" was announced among the top 10 entries of the first semi-final and therefore qualified to compete in the final on 18 May.

Serbia's 2018 entry "Nova deca" performed by Sanja Ilić and Balkanika qualified to the final and placed nineteenth.

The winning entry, "Ljubav je svuda" performed by Moje 3, failed to qualify Serbia to the final at the 2013 Eurovision Song Contest.

The selected competing entries were announced on 10 January 2019 and among the competing artists were Extra Nena, who represented Yugoslavia in the Eurovision Song Contest 1992, and Nevena Božović who represented Serbia in the Junior Eurovision Song Contest 2007 and 2013, the latter as part of the group Moje 3.

[8] In each semi-final twelve songs competed and six qualifiers for the final were decided by a combination of votes from a jury panel consisting of Zoran Lesendrić (musician), Dragomir Stanojević (musician), Nenad Pribak (president of OGAE Serbia), Aleksandar Aleksov (composer and producer) and Ivana Peters (singer-songwriter), and the Serbian public via SMS voting.

[9][10] The final, hosted by Dragana Kosjerina, Ivan Mihailović, Nebojša Milovanović and Ana Babić, took place at the Studio 8 of RTS in Košutnjak, Belgrade on 3 March 2019 and featured the twelve qualifiers from the preceding two semi-finals.

The winner, "Kruna" performed by Nevena Božović, was decided by a combination of votes from a jury panel consisting of Miša Aleksić (musician), Bojana Stamenov (represented Serbia in the Eurovision Song Contest 2015), Dejan Ivanović (lyricist), Goca Tržan (singer) and Aleksandar Milić Mili (composer and producer), and the Serbian public via SMS voting.

On 28 January 2019, a special allocation draw was held which placed each country into one of the two semi-finals, as well as which half of the show they would perform in.

[18][19] Nevena Božović was joined by four off-stage backing vocalists: Ivana Vladović, Olga Popović, Dušan Alagić and Mladen Lukić.

Each nation's jury consisted of five music industry professionals who are citizens of the country they represent, with their names published before the contest to ensure transparency.

This jury judged each entry based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.

In addition, no member of a national jury was permitted to be related in any way to any of the competing acts in such a way that they cannot vote impartially and independently.

The individual rankings of each jury member as well as the nation's televoting results were released shortly after the grand final.
