2021–22 Serie D
The 2021–22 Serie D was the seventy-third season of the top level Italian non-professional football championship. It represents the fourth tier in the Italian football league system.
Rules
The season will provide a total nine promotions to Serie C. Teams placed between second and fifth for each group will play a so-called "playoff tournament", starting with two one-legged games played at the best placed team's home venue:- 2nd-placed team vs 5th-placed team;
- 3rd-placed team vs 4th-placed team.
The two winning teams will then play a one-legged final, to be hosted at the best placed team's home venue, with the same rules as in the first round. The nine playoff winners for each group will be prioritised to fill any potential Serie C league vacancies.
The two bottom-placed teams for each league group are automatically relegated to Eccellenza. Two two-legged relegation playoff games will therefore be played between:
- 13th-placed team vs 16th-placed team, or 15th-placed team vs 18th-placed team ;
- 14th-placed team vs 15th-placed team, or 16th-placed team vs 17th-placed team.
In case the two teams will have a league gap of at least eight points, the relegation playoff will not take place and the worst-placed team will be automatically relegated instead.
