2019–20 Segunda División B

The 2019–20 Segunda División B season was the 43rd since its establishment. Eighty teams participated, distributed in four groups of twenty clubs each. On 11 March 2020, the season of Segunda División B was suspended due to the coronavirus COVID-19 pandemic in Spain.

On 6 May 2020, the Royal Spanish Football Federation announced the premature end of the league, revoking all relegations and planning an eventual promotion playoff to be played if possible. Also, the expansion of the league to five groups of 20 teams each for the 2020–21 season (due to promotion from the curtailed Tercera División groups being applied) was approved.
