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.

Monaco has participated in the Eurovision Song Contest 24 times since its debut in 1959. The country's only win in the contest came in 1971, when Séverine performed "Un banc, un arbre, une rue". As a result, Monaco was expected to host the contest in 1972, but it ultimately declined. Monaco is the only microstate to have won the contest to date.
