The 2023 Tercera Federación play-offs to Segunda Federación from Tercera Federación (promotion play-offs) are the final play-offs for the promotion from 2022–23 Tercera Federación to 2023–24 Segunda Federación.
Group champions will be promoted directly to the Segunda Federación. Due to the remodeling of the RFEF leagues, as of 2021–22 season the promotion play-off is divided into two stages: regional and national. Four teams from each group participate in the regional stage, which were classified between places second and fifth of the regular season. Since 2022–23 season the regional stage is a series of two matches. The second classified will face the fifth classified; and the third will do the same with the fourth. The winners of the two series will play a series to determine the team that will qualify for the national stage.[1]
In the regional phase, if the aggregated score ends in a draw, extra time will be played, if the same result is maintained at the end of extra time, the best seeded team will win.
The national stage will be played by 18 teams, which won their respective regional play-offs. Since 2022–23 season nine different series will be played to determine the winners of the promotion to Segunda Federación.[2]
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.[3]
