The 2016 2. divisjon (referred to as PostNord-ligaen for sponsorship reasons) was a Norwegian football third-tier league season. The league consisted of 56 teams divided into 4 groups of 14 teams. In February 2016 it was announced a change in format, starting in the 2017 season, that would reduce the number of groups from four to two. Therefore, the winners of the four groups will be promoted to the 1. divisjon, while the bottom seven teams in each groups will be relegated to the 3. divisjon.
