The 2019–20 III liga was the 12th 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 4th season under its current league division format.

The competition was contested by 72 clubs split geographically across 4 groups of 18 teams each, with the winners of each group gaining promotion to the II liga.
