The 2025–26 Championnat National 3 was the ninth and last season of the fifth tier in the French football league system in its current format. The competition was contested by 112 clubs split geographically across 8 groups of 14 teams. The teams included amateur clubs (although a few were semi-professional) and the reserve teams of professional clubs. The competition began on 16 August 2025 and ended on 16 May 2026. The fifth tier kept its 8-group format for next season, but was renamed to Championnat National 2, following the establishment of Ligue 3 for the 2026–27 season.

Teams On 17 July 2025, the FFF ratified the constitution of the competition, and published the groups. Following Ajaccio's exclusion from national competitions, and ASPTT Dijon winning their appeal to the French National Olympic and Sports Committee, the Burgundian team will take the Corsican reserve team's place in Group H.
