The 2019 season of the 4. divisjon, the fifth highest association football league for men in Norway.
Between 16 and 26 games (depending on group size) are played in 24 groups, with 3 points given for wins and 1 for draws.
According to a proposal at the 2018 Football Convention, fewer teams would be relegated from the 2019 3. divisjon to the 2020 4. divisjon, and accordingly, fewer teams would be promoted. The groups affected would be the group 1 and 9 winners who would contest a single promotion spot; the group 2–4 winners who would contest two promotion spots; the group 6 and 7 winners who would contest a single promotion spot; the group 8 and 10 winners who would contest a single promotion spot; the group 17 and 18 winners who would contest a single promotion spot; and the group 21 and 22 winners who would contest a single promotion spot.[1] The playoff between the group 21 and 22 winners was cancelled.
Incidentally, the 2020 4. divisjon was cancelled before commencing because of the COVID-19 pandemic in Norway, so the promotions and relegations first came into effect in the 2021 4. divisjon.
