Norway was represented by Ketil Stokkan, with the song '"Brandenburger Tor", at the 1990 Eurovision Song Contest, which took place on 5 May in Zagreb. "Brandenburger Tor" was chosen as the Norwegian entry at the Melodi Grand Prix on 24 March. Stokkan had previously represented Norway in 1986.

The MGP was held at the Hotel Royal Christiania in Oslo, hosted by Leif Erik Forberg. Ten songs took part with the winner chosen by voting from regional juries, an "expert" jury and a press jury. In the first round of voting the bottom five songs were eliminated, then the remaining five were voted on again to give the winner. Other participants included three-time Norwegian representative and MGP regular Jahn Teigen and Tor Endresen, who would represent Norway in 1997.

On the night of the final Stokkan performed 9th in the running order, following Iceland and preceding Israel. The song's subject matter was the fall of the Berlin Wall, and it was only one of several songs in the contest with 'peace, hope and unity' lyrical content. At the close of voting "Brandenburger Tor" had received only 8 points (4 from Israel, 3 from Ireland and 1 from Denmark), placing Norway joint last (with Finland) of the 22 entries. Not even the German jury had been persuaded to vote for the song. This was the seventh time Norway finished the evening at the bottom of the scoreboard. The Norwegian jury awarded its 12 points to France.
