2022–23 Championnat National

The 2022–23 Championnat National season was the 30th since the establishment of the Championnat National, and the 24th in its current format, which serves as third division of the French football league system. Two clubs were promoted to Ligue 2 and six relegated after this season as adjustment for Ligue 1's reduction in size from 20 to 18 next season. As a result, no promotion play-offs were held.

Post-season administrative relegations and reprieves
On 6 June 2023, the DNCG announced administrative relegation to Championnat National 2 for Sedan. Sedan appealed the decision, and the DNCG appeal committee elected to take stronger action, excluding the club from all national championships, effectively relegating the club to the sixth tier. As a result, Nancy were handed a reprieve from relegation.

Nancy themselves were originally handed an administrative relegation by the DNCG, but this was successfully appealed.

Châteauroux were also initially punished with relegation by the DNCG, but successfully appealed and retained their place in the division.

Bourg-Péronnas were initially handed an administrative relegation to Championnat National 3 on top of their sporting relegation, but this was also successfully appealed.
