2020–21 Liga I

The 2020–21 Liga I (also known as Casa Liga 1 for sponsorship reasons) was the 103rd season of the Liga I, the top professional league for Romanian association football clubs. The season started on 21 August 2020 and ended on 19 May 2021. CFR Cluj were winners and three-time defending champions. It was the sixth season to take place in the play-off/play-out format, and the first since the 2005–06 season to feature 16 teams.
The play-off/play-out rule was also altered, with the first six teams at the regular season qualified for the play-off tournament and the last ten for the play-out. The first six teams played two matches against each other as before, but in the play-out the teams only played once against each other. At the end of the play-out, the first two places (or the 7th and 8th overall) played a single match on the ground of the lower ranked team, and the subsequent winner played the last team ranked on a UEFA Europa Conference League spot in the play-off. The winner of the latter encounter qualified for the Europa Conference League.
The teams ranked 15th and 16th at the end of the play-out tournament were directly relegated, while the 13th and 14th places played a promotion/relegation play-off against 3rd and 4th places from Liga II.
The league consists of 16 teams: 13 from the 2019–20 Liga I, two teams from the 2019–20 Liga II, and the winner of the 2019–20 promotion/relegation play-off.
Teams promoted to the Liga I
The first club to be promoted was UTA Arad, following their 1–1 draw against FC Argeș on 2 August 2020. UTA returned in the Liga I after 12 years of absence.
The second club to be promoted was FC Argeș, following their 1–1 draw against UTA Arad on 2 August 2020. FC Argeș returned in the Liga I after 11 years of absence.
Teams relegated to the Liga II
No teams were relegated from the 2019–20 Liga I.
Initially, two clubs would have been relegated at the end of the 2019–20 Liga I season, with a third playing a relegation play-off with the 3rd-placed team from the 2019–20 Liga II. The first club to have been relegated would have been Chindia Târgoviște, following a 0–1 defeat on 2 August 2020 against Politehnica Iași, ending their 1-year stay in the top flight. However, owing to the effects of the COVID-19 pandemic on the previous season, the league table was frozen on 6 August 2020 and no teams were directly relegated. Instead, Chindia Târgoviște played a promotion/relegation play-off against CS Mioveni and kept their Liga I spot after a 3–1 aggregate result.
