Ireland in the Eurovision Song Contest 1975

Ireland was represented by The Swarbriggs, with the song "That's What Friends Are For", at the 1975 Eurovision Song Contest, which took place on 22 March in Stockholm. "That's What Friends Are For" was chosen as the Irish entry at the national final on 9 February.

Competing Entries
RTÉ internally selected The Swarbriggs in October 1974 and opened song submissions. They received 335 entries from public submissions, 295 in English and 40 in Irish. RTÉ chose seven entries from the public submissions and another song was required to be composed by Tommy and Jimmy Swarbrigg, which was "That's What Friends Are For".

Final
The eleventh National Song Contest was held at the studios of broadcaster RTÉ in Dublin, hosted by Mike Murphy. This was the first edition of the National Song Contest to be broadcast in colour. For a second year, RTÉ pre-selected their representatives and The Swarbriggs performed eight songs which were voted on by ten regional juries.
