The 2004âÂÂ05 PBA Philippine Cup, or known as the 2004âÂÂ05 Gran Matador Brandy-PBA Philippine Cup for sponsorship reasons, was the All-Filipino Conference of the Philippine Basketball Association's (PBA) 2004âÂÂ05 season.
The Barangay Ginebra Kings won its first back-to-back titles with a 4âÂÂ2 conquest of the Talk 'N Text Phone Pals. The series was marred by a controversial reversal of the Phone Pals' Game One victory after fielding in an ineligible Asi 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.
Eric Menk won another Best Player of the Conference Award, his third in his PBA career.
The #3 vs. #10 and the #4 vs. #9 matchups are in the "twice-to-beat" format; the team with the higher seed only needs to win once to advance, but needs to be beaten twice in order to be eliminated. The other two matchups are a best-of-three series.
