Denmark participated in the Eurovision Song Contest 2002 with the song "Tell Me Who You Are" written by Michael Ronson. The song was performed by Malene Mortensen. The Danish broadcaster DR organised the national final Dansk Melodi Grand Prix 2002 in order to select the Danish entry for the 2002 contest in Tallinn, Estonia. Ten songs competed in a televised show where "Vis mig hvem du er" performed by Malene Mortensen was the winner as decided upon through two rounds of jury voting and public voting. The song was later translated from Danish to English for the Eurovision Song Contest and was titled "Tell Me Who You Are".
