The 2021–22 Liga III was the 66th season of Liga III, the third tier of the Romanian football league system. The season began in August 2021 and ended on 28 May 2022.
This season was the second consecutive with a format that included 100 teams (10x10). The format was changed before the previous season, due to the financial problems generated by the COVID-19 pandemic.[1] The difference this season is that a play-off and play-out was introduced between the regular season and the promotion play-offs.

The promotion play-offs are disputed between the first two teams from each of the ten play-off round series. Only the best five teams will be promoted to 2022–23 Liga II.
At the end of the season, a special table was made between 8th places from the 10 series. The last team in this table was also relegated in the Liga IV. In this table, 8th place teams are included without the points obtained against teams that relegated in their series.
