The Norwegian Broadcasting Corporation (NRK) organised the national final Melodi Grand Prix 2011 in order to select the Norwegian entry for the 2011 contest in Düsseldorf, Germany. 21 entries competed in the national final that consisted of three semi-finals, a Last Chance round and a final. Eight entries ultimately qualified to compete in the final on 12 February 2011 where the winner was determined over two rounds of voting. In the first round of voting, a public televote exclusively selected the top four entries to advance to the competition's second round—the Gold Final. In the second round of voting, "Haba Haba" performed by Stella Mwangi was selected as the winner following the combination of votes from four regional jury groups and a public vote.
