The 2004–05 PBA season was the 30th season of the Philippine Basketball Association. Instead of the usual calendar year of February–December, the league changed its schedule to the current October–July format, while limiting the number of conferences from three to two. As part of the new league format, the season was preceded with a transition conference known as the 2004 PBA Fiesta Conference.
Opening ceremonies
The muses for the participating teams are as follows:
Barangay Ginebra won its first back-to-back titles and sixth overall crown with a 4-2 conquest over Talk 'N TextPhone Pals. The series was marred by a controversial reversal of the Phone Pals' Game 1 victory after fielding in an ineligible Taulava in the said game. Taulava was serving an indefinite suspension after being cited as one of six Filipino-American players with questionable citizenship papers. The San Miguel Beermen won third place after beating the Shell Turbo Chargers in a one-game match. Eric Menk won another Best Player of the Conference Award, his third in his PBA career. Chot Reyes left his post as the Coca Cola Tigershead coach to become the new coach of the Philippine national basketball team.
