2020–21 Liga IV

The 2020–21 Liga IV was the 79th season of Liga IV and the 53rd since the 1968 administrative and territorial reorganization of the country, representing the fourth tier of the Romanian football league system. The champions of each county association played against one from a neighbouring county in a play-off for promotion to Liga III.

The season was initially postponed due to the high costs generated by COVID-19 pandemic, but on 7 April 2021, the Romanian Football Federation approved a new protocol for the amateur leagues, with lower costs. The county associations had only a month to play a blitzkrieg season, but only 24 leagues (out of 42) had a competition and announced a champion in time, three other county associations (Călărași, Giurgiu and Vrancea) organized a competition, but which ended after the deadline imposed by the FRF.

The promotion play-off was played in two rounds. First round was played between 6 winners of Liga IV (chosen randomly), consisting of 3 matches played on neutral ground. The second round was played as a promotion/relegation play-off, between last two teams of each 2020–21 Liga III series (2X10) and the county leagues winners.
