Radio Television of Serbia (RTS) was responsible for selecting their entry for the contest.

In last year's contest Serbia got a tenth place with Jana Paunović and Irina Brodić and a song called "Ceo svet je naš".

On 13 September 2018, it was announced that Bojana Radovanović would represent the country in Minsk, Belarus with the song "Svet".

After this, voters also had the option to watch longer one-minute clips from each participant's rehearsal.

The second phase of the online voting took place during the live show and began right after the last performance and was open for 15 minutes.
