The Croatian participating broadcaster, Hrvatska radiotelevizija (HRT), organised the national final Dora 2006 to select its entry for the contest.

In the final, "Moja štikla" performed by Severina was selected as the winner following the combination of votes from a five-member jury panel and a public televote.

In 2005, "Vukovi umiru sami" performed by Boris Novković featuring Lado Members managed to qualify to the final where they placed eleventh.
