Croatia participated in the Junior Eurovision Song Contest 2005.

The Croatian broadcaster Hrvatska radiotelevizija (HRT) organised an national final to select the entry, being Lorena Jelusić with the song "Rock Baby".

An expert committee consisting of Nensi Atanasov, Helena Bastić, Davor Gobac, Željen Klašterka, Mladen Kušec, Marin Margitić and Nika Turković selected ten artists and songs for the competition from the received submissions.

For the first time in the history of Croatia's Junior Eurovision selection, the orchestra was dropped and the finalists sang to pre-recorded instrumentation, but were accompanied by in-studio backup singers.
