The 2017–18 Championnat National 3 is the first season of the fifth tier in the French football league system in its current format. The competition is contested by 171 clubs split geographically across 12 groups of 14 teams, 1 group of 15 teams and 1 group of 16 teams. The teams include amateur clubs (although a few are semi-professional) and the reserve teams of professional clubs.
On 13 July, the FFF ratified the constitution of the competition, and published the groups as follows:[1]
On 10 August, the FFF announced that SC Bastia would be denied entry to 2017–18 Championnat National due to financial issues. The club will therefore take the place of its reserve team in Championnat National 3.[4]
On 16 August, the FFF admitted Clémenceau Besançon to the competition. The team had previously been excluded due to financial issues, but successfully appealed the ruling.[5]
On 22 September, the FFF admitted CSO Amnéville to the competition. Amnéville had previously been denied promotion from the Regional Division d'Honneur for financial reasons, and had already started their programme of fixtures in that division.[6]
If eligible, the top team in each group will be promoted to Championnat National 2. If a team finishing top of the group is ineligible, the next eligible team in that group will be promoted.
Generally, three teams will be relegated from each group to the top league in their region, subject to reprieves. Extra relegation places will be enforced if more than one team is relegated to a specific group from Championnat National 2, and one less may be enforced if no team is relegated to a specific group.[7] Special cases exist for those groups which started the year with more than the standard 14 teams.
At least four and up to seven teams will be relegated from Group F, depending on the number of teams from this region relegated from Championnat National 2.[8]
Outcomes below are provisional and subject to ratification by the FFF.
Bordeaux (res), Nantes (res), Blois, Endoume Marseille, Pontarlier, Haguenau, Nîmes (res), Feignies Aulnoye, Oissel, Vannes, Bobigny and Saint-Étienne (res) were promoted to 2018–19 Championnat National 2 as champions of their respective groups.
As of 19 June, all promotions had been verified by the FFF and DNCG[9] [10]
The title of Champion of Championnat National 3 is awarded to the team with the best record in games against the teams that finished in 2nd to 6th place in their group, with goal difference to separate ties.[11]
