The 2023–24 Primera Federación FutFem was the 23rd season of the second highest league tier of women's football in Spain, and the second under that name and using a single group format.
Rayo Vallecano and Granadilla Tenerife B, the clubs in the upper relegation places in 2022–23, indicated they would seek to have the division's reduction from 16 to 14 teams cancelled as it was not properly announced by the RFEF, negating their demotion.
Their appeal to the federation was still awaiting a decision in September 2023 with the new season fast approaching – the clubs publicly expressed their suspicion that their issue had been neglected while the RFEF focused on the Rubiales affair.
[1] The fixtures began as scheduled on 9 September without involvement of the appellants, who played their opening matches in the Segunda Federación a day later.
[4] Two of the newcomers – Europa and Madrid CFF B – were relegated, along with Athletic Club B, whose 21-year stay in the second tier (under various formats) came to an end.
