Norway was represented at the Eurovision Song Contest 1978 with the song "", written by Kai Eide, and performed by Jahn Teigen. The Norwegian participating broadcaster, (NRK), selected its entry through the 1978. Teigen would also represent Norway in and .
"" is famous both for Teigen's notoriously bizarre stage performance in Paris, and for being the first song ever to score nul-points under the 12 points voting system.
