Denmark in the Eurovision Song Contest 2009

Denmark was represented at the Eurovision Song Contest 2009 with the song "Believe Again" written by Lars Halvor Jensen, Martin Michael Larsson and Ronan Keating. The song was performed by Brinck. The Danish broadcaster DR organised the national final Dansk Melodi Grand Prix 2009 in order to select the Danish entry for the 2009 contest in Moscow, Russia. Ten songs competed in a televised show where the winner was selected over three rounds of voting. The results of the first round were decided upon through the combination of jury voting and public voting while the results in the second and third round were determined solely by public televoting. "Believe Again" performed by Brinck was the winner after gaining the most public votes in the third round.

Denmark was drawn to compete in the second semi-final of the Eurovision Song Contest which took place on 14 May 2009. Performing during the show in position 9, "Believe Again" was announced among the 10 qualifying entries of the second semi-final and therefore qualified to compete in the final on 16 May. It was later revealed that Denmark placed eighth out of the 19 participating countries in the semi-final with 69 points. In the final, Denmark performed in position 16 and placed thirteenth out of the 25 participating countries, scoring 74 points.
