The Serbian participating broadcaster, Radio-televizija Srbije (RTS), organised the national final Beovizija 2008 in order to select its entry for the contest.

Twenty entries competed in the semi-final where the top ten qualified to the final following the combination of votes from a three-member jury panel and a public televote.

The ten qualifiers competed in the final which resulted in "Oro" performed by Jelena Tomašević featuring Bora Dugić as the winner following the combination of votes from a three-member jury panel and a public televote.

The selection committee consisted of RTS music editors Ana Milićević, Anja Rogljić, Zoran Dašić, Nikoleta Dojčinović, Jelena Vlahović, Bilja Krstić, and Miki Stanojević.

Guest performers featured Eurovision contestants Laka, Kraljevi ulice and 75 Cents, Tamara with Vrčak and Adrian, Stefan Filipović, Isis Gee, and Rebeka Dremelj, which would represent Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Poland, and Slovenia, respectively.

The show also featured a tribute to former Eurovision contestant, Toše Proeski, who represented Macedonia in 2004 and died in October 2007.

The winner, "Oro" performed by Jelena Tomašević featuring Bora Dugić, was decided by a combination of votes from a jury panel consisting of Petar Janjatović (music journalist), Slobodan Marković (composer) and Nena Kunijević (RTS music editor), and the Serbian public via SMS voting.
