In the Philippine Basketball Association (PBA), the Grand Slam is the achievement of winning all three conference championships (tournaments) in a single season. As of 2020, this has been accomplished five times by four teams and four coaches since the league's inception in 1975.[1]
In the 1970s, 1980s, and 1990s, at least one team swept the championships in one season. The decade 2000–2009 had no Grand Slam winner because of adjustments to the league calendar in 2004, in which the start of the season was moved from January to October and the number of conferences per season was reduced from three to two. The three-conference season format was reinstated in the 2010–11 season.[1]
In the PBA 3x3 tournament, a team can only win the Grand Slam if they win the championships of all three conferences in a season. This feat was first accomplished by the TNT Tropang Giga (later TNT Triple Giga) at the end of the 2022–23 season.[2]
