The Eurovision Song Contest 1990 was the 35th Eurovision Song Contest. It was held on May 5, 1990 in Zagreb, Yugoslavia (now Croatia). The awards presenters were Helga Vlahović and Oliver Mlakar. Toto Cutugno was the winner of this Eurovision with the song "Insieme: 1992".

The lyrics of several entries celebrated the whirlwind of democratisation that had engulfed central and eastern Europe with bewildering speed in the preceding months, focussing especially on the iconic moment of the Berlin Wall being breached in November 1989. However, the winning song was an even more sweeping evocation of European unity, in anticipation of the completion of the European single market, due at the end of 1992.

A notorious mishap occurred at the start of the first song, when a mysteriously long delay caused by problems with the backing track was followed by the Spanish singers missing their cue as the song didn't start from the very beginning. They walked off the stage in barely concealed annoyance and the audience was left in confusion for a moment, but the song was then restarted without any further problems.
