2022–23 Czech First League

The 2022–23 Czech First League, known as the FORTUNA:LIGA for sponsorship reason, is the 30th season of the Czech Republic's top-tier football for professional clubs since its establishment, in 1993. FC Viktoria Plzeň are the reigning champions. The season started on 30 July 2022. The first half of the season will have 16 rounds, finishing on 13 November 2022 because of the 2022 FIFA World Cup, and the other half will commence on 28 January 2023. The season is expected to end on 28 May 2023 with two extra play-out fixtures on 1 and 4 June 2023.

The season format is unchanged from last season, each team will play in the league format home and away matches. The lowest-ranked team will be relegated directly to the second league, the two teams positioned 14th and 15th will play a play-out with two teams from the second league positioned 2nd and 3rd in a home and away format. This will be the fifth season to use VAR, featuring it in all matches played. The year-to-year changes in the format of the competition are only cosmetic, the most significant change being the expansion of the number of substitutes on the substitute bench to 11.
