The Eurovision Song Contest 1981 was the 26th edition of the annual Eurovision Song Contest. It took place in Dublin, Ireland, following the country's victory at the 1980 contest with the song "What's Another Year" by Johnny Logan. Organised by the European Broadcasting Union (EBU) and host broadcaster Radio Telefís Éireann (RTÉ), the contest was held at the RDS Simmonscourt on 4 April 1981, and was hosted by Irish television journalist Doireann Ní Bhriain.

The Eurovision Song Contest 1980 was the 25th edition of the annual Eurovision Song Contest. It took place in The Hague, Netherlands, and was organised by host broadcaster Nederlandse Omroep Stichting (NOS) – which agreed to stage the event after Israel, having won in both 1978 and 1979, declined to host it for a second successive year – and the European Broadcasting Union (EBU). The contest was held at the Nederlands Congresgebouw on 19 April 1980 and was hosted by Dutch actress Marlous Fluitsma, although each song was introduced by a presenter from the participating nation.
