The 2020 2. divisjon (referred to as PostNord-ligaen for sponsorship reasons) was a Norwegian football third-tier league season.
[1] Under normal circumstances, the league would have been played as a double round-robin tournament, where all teams play 26 matches.
However, this season, due to the COVID-19 pandemic, the league was split after 13 rounds, meaning the teams only played each other once in this stage.
[3] On 12 November, four of the last six matches in group 1 were cancelled because the teams had nothing left to play for.
The teams who finished in second place in their respective group qualified for the promotion play-offs, where they faced each other over two legs.
