In Philippine sports leagues, a Grand Slam is the achievement of a team winning all three conferences (or tournaments) in a single season. The term originated in the Philippine Basketball Association (PBA), as a traditional season is composed of three separate conferences rather than a single regular season and postseason. The term has since expanded into other leagues such as the Premier Volleyball League (PVL) and the now-defunct Philippine Basketball League (PBL).

Philippine Basketball Association From 1975 to 2003, and again from 2010 onwards, a traditional Philippine Basketball Association season is composed of three conferences. Currently, these three are the Philippine Cup, Commissioner's Cup, and Governors' Cup.

In certain circumstances, the PBA may hold less than three conferences in a season. To pave the way for the Philippines' hosting of the 1981 SEA Games and 2023 FIBA Basketball World Cup, two conferences were held in the 1981 and 2023–24 seasons. Due to restrictions during the COVID-19 pandemic, the 2020 season was reduced from three conferences to one while only two were held for the following 2021 season.

From 2004 to 2009, the league switched to a two-conference format consisting of the Philippine Cup and the import-laden Fiesta Conference. A Grand Slam can still be achieved by winning both titles but this was never done.San Mig's grand slam victory is destiny fulfilled, Bert A. Ramirez, Rappler, July 13, 2014
