Ireland in the Eurovision Song Contest 1970

Ireland participated in and won the Eurovision Song Contest 1970 with the song "All Kinds of Everything" performed by Dana. John Skehan was the spokesperson for Ireland in the Contest. Valerie McGovern commentated on RTÉ One, and Kevin Roche on RTÉ Radio 1.

National Song Contest
The sixth National Song Contest was due to be held on 8 February 1970 but was postponed until Sunday 1 March 1970 because of a technicians' strike at the national broadcaster. The deadline for countries to submit entries to the EBU for the Eurovision Song Contest 1970 was 23 February 1970, but RTÉ were given a three week extension. Eight entries were chosen out of 397 submissions received by RTÉ. It was broadcast live from the RTÉ studios in Dublin on RTÉ Television, and hosted by Brendan O'Reilly. The winning song was decided by 10 regional juries, each consisting of six members, throughout Ireland.

Dana had previously participated in the Irish national final in 1969, and finished in second place. Both Anna McGoldrick and Tony Kenny had sung in the national contest in 1968.

Voting
Every country had a jury of ten people. Every jury member could give one point to his or her favourite song.
