2019–20 Tercera División

The 2019–20 Tercera División is the fourth tier of Spanish football. It began in August 2019 and was supposed to end in late June 2020 with the promotion play-off finals. On 11 March 2020, the season was suspended due to the COVID-19 pandemic in Spain.

On 6 May 2020, the Royal Spanish Football Federation announced the premature end of the leagues, revoking all relegations and planning an eventual promotion playoff to be played if possible. Each regional federation would be allowed to plan their own group for the 2020–21 season.

Competition format

 * The top four eligible teams in each group will play the promotion playoffs.
 * The champion of each group will qualify to 2020–21 Copa del Rey. If the champion is a reserve team, the first non-reserve team qualified will join the Copa.
 * In each group, at least three teams will be relegated to Regional Divisions.

Copa del Rey qualification
32 teams qualified for the 2020–21 Copa del Rey: the best teams in each group (excluding reserves) and the 14 best second-placed teams ranked by their points coefficient. Should any second-placed team among these 14 qualify already as the best team in its group, a ranking of third-placed teams would fill the remaining vacants.
