The 2021–22 Primera División RFEF season was the first and the only season under the name Primera División RFEF, the new third highest level in the Spanish football league system. It succeeded the old Segunda División B, which renamed itself Segunda División RFEF and downgraded to the fourth level in the pyramid. Forty teams participated, divided into two groups of twenty clubs each based on geographical proximity. In each group, the champions automatically promoted to Segunda División and the second to fifth placers played promotion play-offs and the bottom five were relegated to the Segunda División RFEF.

The 2022–23 Copa del Rey was the 121st staging of the Copa del Rey, the oldest official football competition in Spain. The winners of the competition would have automatically qualified for the 2023–24 UEFA Europa League group stage; however, as Real Madrid had already qualified for European competition via league standings, their place was passed down to the sixth-placed team in La Liga and the UEFA Europa Conference League spot reserved for the sixth-placed team was awarded to the team who finished seventh in the league. Both the winners and runners-up qualified for the four-team 2023–24 Supercopa de España.
