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.
On 6 June 2023, the DNCG announced administrative relegation to Championnat National 2 for Sedan.
[10] 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.
Nancy themselves were originally handed an administrative relegation by the DNCG, but this was successfully appealed.
[12][13] Châteauroux were also initially punished with relegation by the DNCG, but successfully appealed and retained their place in the division.
