The 2015–16 Gazélec Ajaccio season is the 105th professional season of the club since its creation in 1910. This is Gazélec Ajaccio's first season in Ligue 1 after finishing second in the 2014–15 Ligue 2 season.
French teams are limited to four players without EU citizenship. Hence, the squad list includes only the principal nationality of each player; several non-European players on the squad have dual citizenship with an EU country. Also, players from the ACP countries—countries in Africa, the Caribbean, and the Pacific that are signatories to the Cotonou Agreement—are not counted against non-EU quotas due to the Kolpak ruling.
Note: Flags indicate national team as defined under FIFA eligibility rules; some limited exceptions apply. Players may hold more than one non-FIFA nationality.
^Starting this season, Ligue 1 decided to reduce the number of relegation spots from three to two.[4] However, the decision was appealed and overturned so three teams were relegated.[5]
