The Primera Federación, formerly known as Primera RFEF, is the third tier of the Spanish football league system beginning with the 2021–22 season. It is administered by the Royal Spanish Football Federation. It is below the top two professional leagues, the Primera División (also known as La Liga) and Segunda División (also known as La Liga Hypermotion), above the Segunda Federación and Tercera Federación. It is the highest level of semi-professional football in Spain.
In 2020, the Royal Spanish Football Federation announced the creation of three new divisions, two semi-professional and one amateur: the Primera División RFEF as the new third tier of the Spanish system; the Segunda División RFEF as the new fourth tier, broadly using the same format as the Segunda División B created in 1977; and the Tercera División RFEF as the fifth tier, along the same lines as the Tercera División from 1977 whereby groups are limited to teams from each of the nation's autonomous communities and is administered by a local body.
On 30 June 2022, after just one season of existence, Primera División RFEF was renamed to Primera Federación.
