Sixteen entries competed in the national final on 16 February 2019 and "The Dream" performed by Roko was selected as the winner following the combination of votes from ten regional juries and a public televote.

Since 2018, the Croatian entries failed to qualify from the semi-finals; the last time Croatia competed in the final was in 2017 with the song "My Friend" performed by Jacques Houdek.

[2] Between 1993 and 2011, HRT organised the national final Dora in order to select the Croatian entry for the Eurovision Song Contest.

The competition consisted of sixteen entries competing in one final on 16 February 2019 at the Marino Cvetković Sports Hall in Opatija, hosted by Mirko Fodor, Jelena Glišić and Iva Šulentić.

[7] On 20 November 2018, HRT opened a submission period where artists and composers were able to submit their entries to the broadcaster with the deadline on 10 January 2019.

[10] A seven-member expert committee consisting of Ivana Vrdoljak Vanna (singer), Zlatko Turkalj Turki (radio host), Igor Geržina (producer of HRT's Jazz Orchestra), Ante Pecotić (composer and producer), Antonija Šola (singer, actress and composer), Zlatko Gal (music critic) and Željen Klašterka (Head of the Croatian Eurovision Delegation) reviewed the received submissions and selected sixteen artists and songs for the competition.

[11][12] On 29 January 2019, 4 Tenora withdrew their song "Brod bez imena", written by Eduard Botrić and Matko Šimac, due to a previously scheduled concert and replaced with "Nisam to što žele" performed by Kim Verson.

The winner, "The Dream" performed by Roko Blažević, was determined by a 50/50 combination of votes from ten regional juries and a public televote.

[18] On 24 April, Roko performed during the Eurovision Pre-Party, which was held at the Vegas City Hall in Moscow, Russia and hosted by Alexey Lebedev and Andres Safari.

[22] The Croatian performance featured Roko dressed in white jeans, jacket and t-shirt and joined on stage by two dancers with golden wings.

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.
