The 2024 Primera Federación play-offs (Playoffs de Ascenso or Promoción de Ascenso) are the final play-offs for promotion from 2023–24 Primera Federación to the 2024–25 Segunda División.
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.
[1] Starting with the 2022–23 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.
The winners of the two regular season groups will face off in a two-leg final to determine the overall champion.
Deportivo La Coruña win 6–3 on aggregate and were therefore crowned 2023–24 Primera Federación champions.
