Ireland shares a joint record total of seven wins with Sweden, and is the only country to have won three times consecutively.

by Linda Martin (1992), "In Your Eyes" by Niamh Kavanagh (1993), "Rock 'n' Roll Kids" by Paul Harrington and Charlie McGettigan (1994), and "The Voice" by Eimear Quinn (1996).

Ireland, who also finished second with "If I Could Choose" by Sean Dunphy (1967), "Terminal 3" by Linda Martin (1984), "Somewhere in Europe" by Liam Reilly (1990), and "Mysterious Woman" by Marc Roberts (1997), has a total of 18 top five results.

A strike at RTÉ in 1983 meant that the station lacked the resources to send a participant, so it broadcast the contest with the BBC commentary feed.

Ireland was relegated in 2002, but in keeping with EBU rules since they intended to return in 2003, RTÉ broadcast that year's event and a TV commentator was sent to the contest in Tallinn.

Ireland subsequently achieved an unequalled three consecutive victories in the contest: in 1992, the 1984 runner-up Linda Martin returned to win with "Why Me?"

– penned once again by Johnny Logan, giving him a total of three victories as either a performer or writer; in 1993, Niamh Kavanagh was victorious over the United Kingdom's Sonia with "In Your Eyes"; and in 1994, Paul Harrington and Charlie McGettigan won with Brendan Graham's "Rock 'n' Roll Kids".

The winning streak was broken in 1995 when Hiberno-Nordic group Secret Garden, representing Norway, won with the almost entirely instrumental "Nocturne".

At the 2007 contest, Ireland's representatives were Irish folk group Dervish performing "They Can't Stop The Spring"; having automatically qualified for the final, the group finished last with five points (all from Albania, whose jury votes prevented Ireland from achieving its first no-point score), becoming the first Irish entrants to come last in a final.

In 2008, Dustin the Turkey failed to qualify for the final with his song "Irelande Douze Pointe"; the same fate befell Sinéad Mulvey and Black Daisy in 2009.

The country returned to the final in 2024 with Bambie Thug and "Doomsday Blue", and finished in sixth place with 278 points, achieving Ireland's best result since 2000 and breaking Paul Harrington and Charlie McGettigan's record for the most points achieved by an Irish entry in the final.

During the first semi-final of the 2014 contest, it was revealed that the duo Jedward hold two Eurovision records: the highest hair (18.9 cm) and the biggest shoulder pads.

Irish winners Eimear Quinn, Charlie McGettigan and Linda Martin performed as backing singers to most of the songs with Jakob Sveistrup who represented Denmark in 2005.
