Melodi Grand Prix 2021 was the 59th edition of the Norwegian music competition Melodi Grand Prix (MGP). The contest served as the country's preselection for the Eurovision Song Contest 2021. The competition was organized by NRK and was held between 16 January 2021 and 20 February 2021. A total of 26 songs participated – the highest number in the history of the competition.

The competition consisted of five semi-finals, a "wild card" show, and the final on Saturday 20 February 2021. A total of twelve songs participated in the final. Of these, six songs were pre-qualified, while the rest had to qualify through the five semi-finals and the wild card show. All shows were broadcast live from the H3 Arena in Fornebu, just outside Oslo.

The contest was won by the song "Fallen Angel" by Tix. The song therefore represented Norway in the Eurovision Song Contest 2021 in Rotterdam, Netherlands.

The contest was held without an audience due to the COVID-19 pandemic in Norway.

The competition was hosted by the same three presenters as the previous edition: Kåre Magnus Bergh hosted for the seventh time, whereas Ronny Brede Aase and Ingrid Gjessing Linhave hosted the show for the second time. Linhave left the show from the fifth semi-final, citing long-term back problems, and was replaced by Silje Nordnes.
