Iceland in the Eurovision Song Contest 2021

Iceland was represented at the Eurovision Song Contest 2021 in Rotterdam, Netherlands. Icelandic broadcaster Ríkisútvarpið (RÚV) chose Daði og Gagnamagnið to represent the nation with the song "10 Years", written by Daði Freyr Pétursson. Daði og Gagnamagnið were due to compete in the 2020 contest with "Think About Things" before the event's eventual cancellation, having won the 2020 edition of Iceland's national selection Söngvakeppnin. For the 2021 contest, RÚV decided to continue its association with Daði og Gagnamagnið, with the group's 2021 entry being selected internally and as such, no edition of Söngvakeppnin was organised for 2021.

A music video for "10 Years" and a tie-in mobile game were released ahead of the contest to promote the entry. A COVID-19 infection among the members of Daði Gagnamagnið meant that the group were unable to perform "10 Years" live during the contest, however Iceland remained in the competition and competed using rehearsal footage recorded in the contest's arena in the days before the event. Iceland placed 2nd in the second semi-final, held on 20 May 2021, receiving 288 points, and qualified for the final held two days later, where the nation placed 4th with 378 points.
