Qualified teams

The seven first qualified after the first half of the 2017–18 ACB regular season qualified to the tournament. As Herbalife Gran Canaria, host team, not finished between the seven first teams, the eighth qualified did not enter in the Copa del Rey.

Draw

The 2018 Copa del Rey de Baloncesto was drawn on 23 January 2018 at approximately 11:30 and was broadcast live on YouTube and on TV in many countries. The seeded teams were paired in the quarterfinals with the non-seeded teams. There were not any restrictions for the draw of the semifinals. As in recent seasons, the first qualified team plays its quarterfinal game on Thursday.

Threat of strike

In the previous week of the Cup, the Basketball Players Association (ABP) called for a strike on 14 February, thus trying to stop the Cup if the ACB do not accept their requirements, in the negotiation of the new collective agreement, including the subsidy of €315,000 from the league to the players' trade union.

After the trade union's proposal, several clubs refused to follow the strike. However, many players are supporting the Players' Association by social networks. Finally, on 13 February, ACB and ABP agreed terms and the Cup would be played normally.
