The 2020–21 Liga IV was the 79th season of the Liga IV, the fourth tier of the Romanian football league system. 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.
