2023 Primera Federación play-offs

The 2023 Primera Federación play-offs (Playoffs de Ascenso or Promoción de Ascenso) are the final play-offs for promotion from 2022–23 Primera Federación to the 2023–24 Segunda División.

Format
Teams ranked second through fifth in each of the two groups will qualify for the promotion play-off, which will determine the last two promotion spots. The eight qualified teams will be drawn into two fixed brackets, each of which will contain the second and fourth-place finishers from one group and the third and fifth-place finishers from the other. All ties will consist of a two-legged knockout series. In case of draws, an overtime period will be played; if the match is still tied following the overtime, the team which achieved a higher regular season finish will be proclaimed the winner.

As of this season, the RFEF recovered the two-legged knockout system, due to the complaints filed against the single knockout system at a neutral venue that had been implemented after COVID-19 and the subsequent reform of the football leagues organized by the RFEF.
