Tercera División (English: Third Division) was the fourth tier of the Spanish football league system.

[1] Tercera División featured 360 teams divided into 18 regional groups, corresponding to the autonomous communities of Spain (due to its size, Andalusia is divided into two groups, East and West; Ceuta is allocated to West Andalusia, while Melilla is allocated to the East).

The eighteen group champions also qualified for the following season's Copa del Rey, of which reserve teams were ineligible.

Whenever there was a tie in position (like the group winners in the champions' series or the third-placed teams in the first round), a draw determined the club to play at home first.

Thus, the top four teams in each group at the time of suspension were deemed to qualify for the play-offs, which will be contested on a regional basis at neutral venues.

The eight group winners qualified for a play-off and CD Castellón eventually beat Barakaldo CF 3-2 to be declared champions.
