Ligue Professionnelle 1 Format: 16 Clubs, 30 Matchdays
The Tunisian Ligue Professionnelle 1 is the country's top division, contested by 16 clubs over 30 matchdays in a double round-robin from August to May.
The champion and runner-up enter the CAF Champions League, while third place and the Tunisian Cup winner go into the CAF Confederation Cup. The bottom three clubs are relegated to Ligue Professionnelle 2, with three promoted in their place.
The league expanded from 14 to 16 teams in 2024 and has been fully professional since 1994–95, when the National Professional Football League took over what had been an amateur national championship since independence.
