2025–26 Serie D
The 2025–26 Serie D will be the seventy-eighth 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 of 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 playoff winners will be prioritized to fill a potential Serie C league vacancy.
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 have a league gap of at least eight points, the relegation playoff will not take place and the worst-placed club will be automatically relegated instead.
Teams
The league's composition involves nine divisions, grouped geographically and named alphabetically.Teams relegated from Serie C
The following teams were relegated from the 2024–25 Serie C:- From Group A: Union Clodiense Chioggia, Caldiero Terme

In addition, SPAL submitted an incomplete and invalid application to the league, and was subsequently excluded, replaced by the playoff-winning team Ravenna. Consequently, the number of clubs in Serie D decreased from 165 to 164.

Promoted as national playoff winners.
Admitted as repechage to fill a vacancy.
As usual, there was an interchange of 36 clubs between Serie D and Eccellenza. However, as both the winners, finalists, and semifinalists of the Coppa Italia Dilettanti had already won promotion to Serie D, they were not eligible for the additional spot commonly assigned to the tournament.
The spot was consequently vacated, reducing the number of clubs from 164 to 163 teams. Moreover, the Eccellenza Molise winners, Vastogirardi, did not apply for a Serie D spot, thus reducing the number to 162, the standard membership for this season. Successively, due to financial issues, three more clubs were rejected, Matera, Avezzano, and Eccellenza's playoff winners Castelnuovo Vomano, and they were replaced by:
- two Serie D's playouts losers ;
- the best Eccellenza's playoff losers.
Relocations, mergers and renamings
- Città di Varese was renamed to Varese;
- Cynthialbalonga was renamed to Albalonga, renouncing the joint representation of Albano Laziale and Genzano di Roma in order to represent only the former city.
- Nola replaced Puteolana, acquiring the sports rights of the latter.
