The Croatian participant broadcaster in the contest is Hrvatska radiotelevizija (HRT), which has selected its entrant at the Dora festival since 1993, excluding from 2012 to 2018.

Croatia achieved six top ten results in seven years, with "Nostalgija" performed by Magazin and Lidija finishing sixth (1995), "Sveta ljubav" by Maja Blagdan fourth (1996), "Neka mi ne svane" by former Magazin member Danijela Martinović fifth (1998), "Marija Magdalena" by Doris Dragović fourth (1999), "Kad zaspu anđeli" by Goran Karan ninth (2000), and "Strings of My Heart" by Vanna tenth (2001).

A period of 23 years without a top ten result followed, which was interrupted by a second-place finish in 2024 with "Rim Tim Tagi Dim" by Baby Lasagna.

Hrvatska radiotelevizija (HRT) is a full member of the European Broadcasting Union (EBU) since 1 January 1993, thus eligible to participate in the Eurovision Song Contest since then.

HRT announced on 19 September 2013 that they would not participate in the 2014 contest, citing the financial difficulties, as well as a string of poor results between 2010 and 2013 influencing their decision to take a year's break.

[13] Jacques Houdek, the coach of Nina Kraljić in The Voice, was internally selected to represent the country on 17 February 2017, exactly five months after they confirmed the participation.

On 30 October 2018, it was announced by HRT that the national final, Dora, would return in 2019, traditionally taking place in Opatija, a famous summer resort.

[16] Damir Kedžo won the 2020 edition of Dora with "Divlji vjetre", but did not represent Croatia due to the 2020 contest's cancellation caused by the COVID-19 pandemic.

[17] Baby Lasagna won with "Rim Tim Tagi Dim" and achieved the country's best result to date, having placed second at the 2024 contest.

The delegation, whose size can greatly vary, includes a head of press, the contestants, songwriters, composers and backing vocalists, among others.

[30] From 1961 until 1991, Croatia was part of Yugoslavia and TV Zagreb, the affiliate of JRT in the socialist republic, broadcast the contest with Croatian commentary.
