The 2021 Úrvalsdeild karla, also known as Pepsi Max deild karla for sponsorship reasons, was the 110th season of top-flight Icelandic football. Twelve teams contested the league, including the defending champions Valur, who won their 23rd league title in 2020.
The 2021 Úrvalsdeild was contested by twelve teams, ten of which played in the division the previous year and two teams promoted from 1. deild karla. The bottom two teams from the previous season, Grótta and Fjölnir (both relegated after one year in the top flight), were relegated to the 2021 1. deild karla and were replaced by Keflavík (promoted after a two-year absence) and Leiknir (promoted after a five-year absence), champions and runners-up of the 2020 1. deild karla respectively.
