The Irish participating broadcaster, Raidió Teilifís Éireann (RTÉ), organised the national final Eurosong 2024 in order to select its entry for the contest.

Ireland holds the record for being the only country to win the contest three times in a row (in 1992, 1993, and 1994), as well as having the only three-time winner (Johnny Logan, who won in 1980 as a singer, 1987 as a singer-songwriter, and again in 1992 as a songwriter).

In 2011 and 2012, Jedward represented the nation for two consecutive years, managing to qualify to the final both times and achieve Ireland's highest position in the contest since 1997 Marc Roberts, placing eighth in 2011 with the song "Lipstick".

[3] Eurosong 2024 was the national final format developed by RTÉ in order to select its entry for the Eurovision Song Contest 2024.

[6] On 15 June 2023, RTÉ opened a submission period where artists and composers would be able to submit their entries for the competition until 29 September 2023; shortly before the closing, the deadline was extended until the following 20 October.

[8] The competing entries were selected by a jury panel with members appointed by RTÉ among music industry professionals and Eurovision fans and presided by Kealy, both from the received submissions and by direct invitation of established artists.

The international jury panel consisted of Luxembourgish head of delegation Eric Lehmann, Finnish executive producer Anssi Autio [fi] of Yle, Austrian music manager Kerstin Breyer and British journalist Deban Aderemi of Wiwibloggs, while the national jury panel consisted of songwriter Niall Mooney, radio DJ Tara Murray, music consultant Elaine McCann and RTÉ 2fm presenter Tracy Clifford; the televote points were announced by 2022 Irish representative Brooke Scullion.

Bambie Thug with "Doomsday Blue" was proclaimed the winner with a total of 32 points, having received the top score from both the national jury and the public vote.

[26] While not mentioning Israel's participation in the contest, on 29 March 2024, Bambie Thug released a joint statement with other Eurovision 2024 entrants – namely Gåte (Norway), Iolanda (Portugal), Megara (San Marino), Mustii (Belgium), Nemo (Switzerland), Olly Alexander (United Kingdom), Saba (Denmark), Silvester Belt (Lithuania) and Windows95man (Finland) – calling for "an immediate and lasting ceasefire" in Gaza as well as the return of the Israeli hostages held by Hamas.

[37] Their performance of "Doomsday Blue" at the contest is staged by Sergio Jaén and choreographed by Matt Williams,[38] and sees the presence of a dancer as well as the usage of candles, smoke and flames.

[40] The singer performed in their first dress rehearsal with the words 'ceasefire' and 'freedom for Palestine' written in Ogham script on their face and leg; the EBU had them remove those messages from the costume in order "to protect the non-political nature of the event".

[46] The Irish jury consisted of Tracy Clifford, Kim Hayden, Bill Hughes, Lisa Lambe, and Brian Sheil.

[48][49] RTÉ appointed Paul Harrington, who won the 1994 contest for Ireland, as its spokesperson to announce the Irish jury's votes in the final.

Each participating broadcaster assembles a five-member jury panel consisting of music industry professionals who are citizens of the country they represent.
