The 2022–23 Slovenian Basketball League, also known as Liga Nova KBM due to sponsorship reasons, is the 32nd season of the Premier A Slovenian Basketball League.
Format
Regular season
In the first phase, ten teams compete in a home-and-away round-robin series (18 games total). Teams advanced from the regular season to one of two postseason stages, depending on their league position.
Second phase
The top five teams from the regular season advanced to the championship phase. Cedevita Olimpija start their competition from this phase.

The last five teams enter a home-and-away round-robin playout-league where two best teams qualify to quarterfinals.
