Denmark participated in the Eurovision Song Contest 2011 in Düsseldorf, Germany, selecting their entry through the national final Dansk Melodi Grand Prix 2011, organised by Danish broadcaster Danmarks Radio (DR).
Less than a week after the Eurovision Song Contest 2010 concluded, Danish broadcaster DR started preparing the 2011 edition of its national selection, Dansk Melodi Grand Prix. As in recent years, the selection was a one-off event.
Ten songs competed in one show where the winner was determined over three rounds of voting. In the first round, the top four songs based on the combination of votes from a public SMS vote and a six-member jury panel qualified to a second round of voting. In the second round, the four qualifiers competed against each other in two duels, with SMS voting selecting the winner of each duel to progress to the final round. In the final round, the winner was determined exclusively by SMS voting.
Songs could be submitted to DR until 27 September 2010. Performers or songwriters were required to hold Danish citizenship or have correspondingly strong relationships with Denmark, while there was no restriction on the language of the entries. The broadcaster received 663 entries, 101 songs more than the previous year. A preliminary jury selected seven songs from the entries submitted to the broadcaster, while an additional three acts: Anne Noa, Jenny Berggren and Stine Kinck, were invited by the broadcaster to compete based on editorial considerations. The competing artists and songs were announced on 3 February 2011.
The final took place on 26 February 2011 at the Ballerup Super Arena in Ballerup (a north-western suburb of Copenhagen), hosted by Felix Smith and Lise Rønne. In the first round of voting, the votes of a jury (50%) and a public vote (50%) determined the top four to advance to the second round: "Sleepless" performed by Anne Noa, "25 Hours a Day" performed by Le Freak, "Hvad hjertet lever af" performed by Stine Kinck and "New Tomorrow" performed by A Friend In London. In the second round of voting, the four qualifiers competed against each other in two duels, with a public vote selecting the winner of each duel to progress to the final round: "Sleepless" performed by Anne Noa and "New Tomorrow" performed by A Friend In London. In the final voting round, the winner, "New Tomorrow" performed by A Friend In London, was selected solely by a public vote.
Denmark performed in the second half of the second semi final of the contest, with starting position 18 on the 12th of May 2011. Denmark qualified for the grand final on May 14, 2011, placing 2nd with 135 points. Shortly after the completion of the second semi final, Denmark drew starting position 3 for the grand final on Saturday night. After a solid performance from the Danes, and at the completion of the voting, they finished 5th with 134 points rounding out the top 5.
