Bastia and Ajaccio will play their two Corsican derbies next season behind closed doors because of trouble during their matches this campaign.
The French Football League's (LFP) Disciplinary Commission handed down the order, adding that both games will have to be played at a neutral venue.
The decision comes following a brawl between the teams in Bastia on March 2, when a total of five players were sent off.
After the match, five Ajaccio and two Bastia fans were injured in the violence that broke out in the stands.
The match at Ajaccio on October 21 ended with 20 players on the bench, after one player from each team was sent off for fighting, leading to clashes between police and Bastia supporters.
