2023–24 Slovenian PrvaLiga

The 2023–24 Slovenian PrvaLiga was the 33rd edition of the Slovenian PrvaLiga since its establishment in 1991. The season began on 22 July 2023 and ended on 19 May 2024. Olimpija Ljubljana were the defending champions after winning their third title in the previous season.

Celje won their second PrvaLiga title with three rounds to go after defeating Olimpija 1–0 on 28 April 2024. As champions, they qualified for the first qualifying round of the 2024–25 UEFA Champions League. Maribor, which finished as runners-up, qualified for the first qualifying round of the 2024–25 UEFA Europa League instead of Slovenian Cup winners Rogaška, which failed to obrain competition licence and were thus relegated. The third-placed and the fourth-placed teams, Olimpija and Bravo, entered the second and first qualifying round of the 2024–25 UEFA Conference League, respectively. Aluminij were relegated to the Slovenian Second League as the bottom-placed team, together with eight-placed Rogaška.

Teams
Olimpija Ljubljana entered the season as defending champions after winning their third title in the previous season. Gorica and Tabor Sežana were relegated at the end of the previous season. They were replaced by Aluminij and Rogaška, who joined the remaining eight teams this season after promotion from the Slovenian Second League. Aluminij returned to the first division after a one-year absence, while Rogaška made their PrvaLiga debut.

PrvaLiga play-off
The ninth-placed club of the PrvaLiga, Radomlje, should have played a two-legged play-off against the second-placed club from the 2023–24 Slovenian Second League, Nafta 1903, for the final place in the following season's PrvaLiga. However, the Football Association of Slovenia cancelled the play-offs on 22 May 2024, as Rogaška, which finished eighth in the PrvaLiga, did not obtain a competition licence and were relegated. As a consequence, both Radomlje and Nafta 1903 earned a place in the 2024–25 Slovenian PrvaLiga season.
