Melodifestivalen 2006 was the selection for the 46th song to represent Sweden at the Eurovision Song Contest. It was the 45th time that this system of picking a song had been used. Five semifinals had taken place to select the ten songs for the final, in Leksand, Karlstad, Karlskrona, Gothenburg and a Second Chance round in Stockholm. The final was broadcast on SVT1 and Sveriges Radio's P4 network. Carola Häggkvist was the clear favourite to win the final , with bookmakers making her favourite and an Aftonbladet web poll showing her to have a clear margin over the other participants. The rehearsals sold out for the fourth year running , however Carola was unable to perform in the final rehearsal due to throat problems . This led to speculation that the final would be closer than expected. Aftonbladet claimed in April 2006 that the televote may have been tampered with , as various sources reported unexplained voting (predominantly for Carola) on their telephone bills. It is clear that this would not have affected the result. Various finalists and semifinalists entered the Swedish Hitlistan chart after the competition . The second placed song, "Temple of Love" finished fourth in the Eurovision Madrid National Finals Song Contest.
The semifinals for Melodifestivalen 2006 began on 18 February 2006. Ten songs from these semifinals qualified for the final on 18 March 2006. This was the fifth year that a semifinal format had been used for the competition, and interest was higher than ever.
