Prior to the start of the season, the rules of the Spanish Basketball Federation established that the top seven teams classified after the end of the first half of the 2018–19 League (13th matchday, 30 December 2018), would play the competition along with the host chosen by the Federation.[2]
The Cup was drawn on 15 February 2019 in Vitoria-Gasteiz. The seeded teams were paired in the quarterfinals with the non-seeded teams. There were not any restrictions for the draw of the semifinals.[3]
