Norway in the Eurovision Song Contest 2018

Norway was represented at the Eurovision Song Contest 2018 with the song "That's How You Write a Song", written and performed by Alexander Rybak, who had previously represented the country in the Eurovision Song Contest in 2009 and won with the song "Fairytale". The Norwegian participating broadcaster, Norsk rikskringkasting (NRK), organised the national final Melodi Grand Prix 2018 in order to select the Norwegian entry for the contest. Ten entries competed in a show that took place on 10 March 2018 and the winner was determined over three rounds of voting.

Norway was drawn to compete in the second semi-final of the Eurovision Song Contest which took place on 10 May 2018. Performing as the opening entry during the show in position 1, "That's How You Write a Song" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 12 May. It was later revealed that Norway placed first out of the 18 participating countries in the semi-final with 266 points. In the final, Norway performed in position 7 and placed fifteenth out of the 26 participating countries, scoring 144 points.
