Final
FC Barcelona won its 13th title after beating in the final CB Inmobanco. Previously, Real Madrid boycoted the semifinal against Barcelona due to the non-signature of the creation of the ACB by the Catalans.

As Barcelona won the Liga Nacional, Inmobanco qualified to the Cup Winners' Cup as runner-up, but finally was dissolved before the start of the next season.
