Ireland in the Eurovision Song Contest 2003

Ireland was represented at the Eurovision Song Contest 2003 with the song "We've Got the World", written by Martin Brannigan and Keith Molloy, and performed by Mickey Harte. The Irish participating broadcaster, Radio Telefís Éireann (RTÉ), organised the competition You're a Star in order to select its entry for the contest. The broadcaster returned to the contest after a one-year absence following their relegation in 2002 as one of the bottom six entrants in 2001. The competition consisted of 20 shows and concluded with a final, resulting in the selection of "We've Got the World" performed by Mickey Joe Harte as the Irish Eurovision entry after facing a public televote.

Ireland competed in the Eurovision Song Contest which took place on 24 May 2003. Performing during the show in position 3, Ireland placed eleventh out of the 26 participating countries, scoring 53 points.
