The 2019–20 Liga III was the 4th season, since its introduction in 2016, of the third level women's football league of the Romanian football league system. The number of starting teams in Liga III increased from 18 to 19. Therefore, 19 teams divided in 4 series (of 4 or 5 teams) were to play in the competition that consists of a double round-robin lasting 6 or 10 stages, totalling 72 matches. Since one team withdrew before the start of the competition, the total number of matches to be played became 64. However, only 44 games were played until the season was frozen due to the 2019-20 coronavirus pandemic.
