The Eurovision Song Contest 1990 was the 35th edition of the Eurovision Song Contest, held on 5 May 1990 in the Vatroslav Lisinski Concert Hall in Zagreb, Yugoslavia. Organised by the European Broadcasting Union (EBU) and host broadcaster Radiotelevizija Zagreb on behalf of Jugoslavenska radiotelevizija (JRT), and presented by Oliver Mlakar and Helga Vlahović, the contest was held in Yugoslavia following the country's victory at the 1989 contest with the song "Rock Me" by the group Riva. It was the first contest to be held in the Balkans and the first to be held in a socialist state.
