Idol 2020 was the sixteenth season of the Swedish Idol series.^[1] Like earlier seasons, the season was broadcast on TV4. New for this year is that one person got to audition for this season already during the final of Idol 2019 in Globen, Rebecka Assio made it through to the final audition in Stockholm.^[2]

On 22 September, contestant Caspar Camitz tested positive for COVID-19 and would miss the first Top 13 performance.^[3] On 25 September, just a few hours away from the airing of the first Friday show, Affe Hagström, Nadja Holm and Herman Silow also tested positive for the virus, which led to changes to the week's show. The contestants therefore performed their songs from their suites at their hotel.^[4] Affe Hagström, who was going to sing the song "Sun Is Shining (Band of Gold)" by Vargas & Lagola, made the decision to not perform that week.

On 26 September, it was announced that contestant Indra Elg, who just had left the competition one day earlier, also tested positive for COVID-19, just like Caspar Camitz, Affe Hagström, Nadja Holm and Herman Silow.^[5]

On 16 October, just a few hours away from airing the fourth Friday show, contestant Affe Hagström made the decision to leave the competition.

On 12 November, it was announced that, just because of COVID-19, the final would not be held in the Globen Arena on 4 December, like it has been since 2007, and would instead be held in the Idol Studio in Spånga. It is the first time since 2006 that the final has been held in the Idol Studio.

Nadja Holm and Paulina Pancenkov made it to the final on 4 December.^[6] Nadja Holm was the winner.^[7] It was also Nikki Amini's last season as a judge member of the show, which means that she would no longer be a part of the show. She was later replaced by Katia Mosally, who has been a judge member since the season of 2021 and onwards.
