2024–25 III liga

The 2024–25 III liga (also known as Betclic III liga for sponsorship reasons) is the 17th season of the fourth tier domestic division in the Polish football league system since its establishment in 2008 under its current title (III liga) and the 8th season under its current league division format. The league is operated by the Polish Football Association (PZPN).

The competition is contested by 72 clubs split geographically across 4 groups of 18 teams, with the winners of each group gaining promotion to the II liga. The season is played in a round-robin tournament. It will begin in 2024 and will conclude in 2025. The teams include semi-professional clubs (although a few are professional) and the reserve teams of professional clubs.
