2019–20 Czech First League

The 2019–20 Czech First League, known as the Fortuna liga for sponsorship reasons, was the 27th season of the Czech Republic's top-tier football league. The defending champions were Slavia Prague, who won their fifth Czech title in the previous season. This season was the second one with a new league structure in which 16 clubs play each other home and away, until the league is split up in championship, Europa League and relegation groups.

Season events
On 12 March, the League Football Association announced that all Fortuna liga games had been postponed for the foreseeable future due to the COVID-19 pandemic.

After 2 months, on 12 May, the League Football Association announced that the Fortuna liga would resume on 25 May. The regular season concluded on 14 June 2020.

On 23 July, when the Champions group and the Europa League playoffs had already been finalized, SFC Opava - a team holding 15th place in the table had a suspected coronavirus case among their team members. The Czech League Football Association said it was not possible to complete the league's relegation group as a result of this, and the team was forced to quarantine. None of the three teams in danger of being relegated to the second league, namely Karviná, Opava and Příbram, would be relegated. From the Second League, the victorious Pardubice, and second-placed Zbrojovka Brno would advance to the first league, while third-placed Dukla Praha would not. The relegation group matches were suspended and no team was relegated.

Results
Each team plays home-and-away against every other team in the league, for a total of 30 matches played each.

Championship group
Points and goals were carried over in full from the regular season.

Europa League play-offs
Teams placed between 7th and 10th position will take part in the Europa league play-offs. The best of them will play against the fourth-placed or fifth-placed of the championship play-offs to determine the Europa League play-off winners. The winners will qualify for the second qualifying round of the 2020–21 UEFA Europa League.

Relegation group
Points and goals were carried over in full from the regular season. The relegation group was scheduled to conclude on 7 July but due to three players from MFK Karviná testing positive for COVID-19, the last two rounds of matches were postponed to 23 and 26 July. Then, due to one player from SFC Opava testing positive for COVID-19, the last two rounds of matches were not played. As a consequence, no team was relegated and number of teams for 2020–2021 season was increased from 16 to 18.
