2024–25 Segunda Federación

The 2024–25 Segunda Federación season will be the fourth for the Segunda Federación, the fourth highest level in the Spanish football league system. Ninety teams will participate, divided into five groups of eighteen clubs each based on geographical proximity. In each group, the champions automatically promoted to Primera Federación, and the second to fifth placers will play promotion play-offs. The last five teams in each group will be relegated to the Tercera Federación; in addition, the four worst teams classified 13th in their group will play play-offs to define the last two relegation places.

Overview before the season
A total of 90 teams will join the league: ten relegated from the 2023–24 Primera Federación, 53 retained from the 2023–24 Segunda Federación and 27 promoted from the 2023–24 Tercera Federación. The groups were defined by the RFEF on 2 July 2024.

On 4 July 2024, RFEF confirmed the administrative relegation of Ursaria due to financial issues.
