The PBA Philippine Cup is one of three active conferences in the Philippine Basketball Association (PBA). In this conference, only Filipino players and players of Filipino descent can compete, meaning that imports are not allowed. Before the 2004–05 season, the tournament was known as the PBA All-Filipino Cup. It is considered the most prestigious of the three conferences in a PBA season.
Since the 2006–07 season, the champions of the Philippine Cup are awarded the Jun Bernardino Trophy, named after former PBA commissioner Jun Bernardino, which they get to keep possession of until the next Philippine Cup champion is crowned. If a team wins three Philippine Cups in a row, that team will have permanent possession of the trophy.
The 1975 and 1976 editions of the tournament were reclassified as an import-laden conference since the league gave the lower-ranking teams the option of hiring imports to bolster their respective lineups. The first tournament that prohibited teams from hiring foreign players or imports was held in 1977. The 1981 and 1982 seasons did not have an All-Filipino Conference.
The Meralco Bolts are the current defending Philippine Cup champions, winning their first in the 2024 PBA Philippine Cup. The San Miguel Beermen have won the most Philippine Cup titles with ten.
