Ireland selected its entry for the Eurovision Song Contest 2010 by a national selection on 5 March 2010. After an open call for songs, Ireland's national broadcaster Raidió Teilifís Éireann (RTÉ) announced on 10 February the five participants who would compete in Eurosong 2010, the selection process.

Ireland has participated in the Eurovision Song Contest forty-three times since the country's first entry in 1965, winning a total of seven times - in 1970 with the song "All Kinds of Everything" performed by Dana; two wins for Johnny Logan in 1980 and 1987 with the songs "What's Another Year" and Hold Me Now"; in 1992 with the song "Why Me?" performed by Linda Martin; in 1993 with the song "In Your Eyes" performed by Niamh Kavanagh; in 1994 with the song "Rock 'n' Roll Kids" performed by Paul Harrington and Charlie McGettigan; and in 1996 with "The Voice" performed by Eimear Quinn - a record which no country has ever matched or beaten. In recent years, however, Ireland's impressive record at Eurovision has taken a turn, with only two Top 10 results during the 2000s, and Ireland's first last place finish in 2007, "They Can't Stop The Spring" performed by Dervish which only received 5 points.

The Irish national broadcater, RTÉ, hosts the event each year and organizes the selection process for its entry. Many methods of selection have been used, with the most common method used by RTÉ being a national final featuring a multi-artist, multi-song selection in which regional juries, and later the public, choosing the winner. In previous years the artist has sometimes been selected internally by RTÉ, with the song being chosen by the public, and previously a talent show format, You're a Star, was used between the years 2003 and 2005.
