The 2025–26 III liga (also known as Betclic III liga for sponsorship reasons) will be the 18th 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 ninth season under its current league division format. The league is operated by the Polish Football Association (PZPN).
The competition is expected to be 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, culminating in promotion/relegation play-offs involving two second-placed III liga teams facing II liga clubs that finish their season in 13th and 14th.
