Robinson 2021, also known as Robinson Sverige (English: Robinson Sweden), is the twentieth season of Robinson. For the first time in the show's history, due to the COVID-19 pandemic, the season was filmed within Sweden at Seskar-Furö in Haparanda and Halsön-Kallskär in Kalix.^[2] The season is broadcast on TV4 and Anders Öfvergård is again the presenter.^[3]

The 12 initial contestants, divided into team South and team North, were revealed on 9 March 2021.^[4] Alexander and Elias started as 'moles' in team South and team North, respectively, meaning they belonged to the opposite team until after the first Robinson challenge and earned immunity in the first week's vote if they didn't get revealed as moles. Both passed and completed the mole task.

From Day 19, contestants that are eliminated are sent to The Borderlands to fight their way back to the merge. On Day 20, four new contestants (Anna, Rickard, William and Wilma) appeared and competed in a challenge to decide which two would join the competition and which two would be sent to Gränslandet (English: The Borderlands). Rickard and William won and were ordered to choose their team members for their new tribes in alternating order, as captains of their tribes, with William choosing first as he finished first. They were also immune at the first week's tribal council. When there was only one person left to choose, that person (Tova-Sophia) was sent to The Borderlands as well.

Alexander and Tova-Sophia were disqualified after eating food purchased outside the show.

Note: Cycle 4 was the last cycle during the Original Tribe period, and Cycle 5 the only cycle during the Intruder's Tribe period.

Note: The "Blood Revenge" (previously named "Black Hand") is a vote given by a voted-out person to one of the remaining contestants in their team which applies to that person in its next vote.
