Ireland in the Eurovision Song Contest 1974

Ireland was represented at the Eurovision Song Contest 1974 with the song "Cross Your Heart", written by Paul Lyttle, and performed by Tina Reynolds. The Irish participating broadcaster, Radio Telefís Éireann (RTÉ), selected its entry through a national final, after having previously selected the performer internally.

For the first time since joining Eurovision in 1965, RTÉ pre-selected Reynolds as its performer rather than holding a multi-artist selection. It is generally believed that this was in acknowledgement of Reynolds' co-operation with RTÉ during the well-publicised controversies and disagreements which had dogged the Irish participation in 1973.
