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.
