Melodifestivalen 2020 was the 60th and most recent edition of the Swedish music competition Melodifestivalen. The competition was organised by Sveriges Television (SVT) and took place over a six-week period between 1 February and 7 March 2020. The winner of the competition would have represented Sweden in the Eurovision Song Contest 2020, which would have been held in Rotterdam, Netherlands. The Mamas are the first band to win since 2007 and the first female act to win since 2014; this is the fourth time in the history of Melodifestivalen that Sweden was unable to send a song to the Eurovision Song Contest (and the first such occurrence since 1976), as the contest itself was cancelled on 18 March 2020 due to the COVID-19 pandemic.
The format of the competition consisted of 6 shows: 4 semi-final rounds, a second chance round and a final. An initial 28 entries were selected for the competition through three methods: an open call for song submissions, direct invitations to specific artists and songwriters, and a wildcard given to one of the artists that participated in the P4 Nästa competition organised by Sveriges Radio P4. The 28 competing entries were divided into four semi-finals, with seven compositions in each. From each semi-final, the songs that earn first and second place qualify directly to the final, while the songs that place third and fourth proceed to the Second Chance round. The bottom three songs in each semi-final were eliminated from the competition. An additional four entries qualified from the Second Chance round to the final, bringing the total number of competing entries in the final to 12. All 6 shows were hosted by Lina Hedlund, Linnea Henriksson and David Sundin.
Melodifestivalen 2020, organised by Sveriges Television (SVT), was the nineteenth consecutive edition of the contest in which the competition took place in different cities across Sweden; this was the last time that the event was held in this format. The four semi-finals were held in the Saab Arena in Linköping (1 February), the Scandinavium in Gothenburg (8 February), the Coop Norrbotten Arena in Luleå (15 February) and the Malmö Arena in Malmö (22 February). The Second Chance round took place in the Stiga Sports Arena in Eskilstuna on 29 February, while the final was held in the Friends Arena in Stockholm on 7 March. A total of 28 entries competed in the semi-finals, with seven entries taking part in each show. The top two entries from each semi-final advanced directly to the final, while the third and fourth placed entries advanced to the Second Chance round. The bottom three entries in each semi-final were eliminated. An additional four entries qualified for the final from the Second Chance round, bringing the total number of competing entries in the final to 12.
The twenty-eight competing entries were announced to the public during a press conference on 26 November 2019. On 2 February 2020, it was announced that Thorsten Flinck would be disqualified from the competition due to the fact that criminal charges of unlawful threat and vandalism had been filed against him. One day later, Jan Johansen was announced as his replacement.
