2023–24 PBA 3x3 season

The 2023–24 PBA 3x3 season is the third and last season of the PBA 3x3, the 3x3 basketball league of the Philippine Basketball Association.

Teams
All 12 franchise teams of the main 5-a-side Philippine Basketball Association are eligible to field a 3x3 team for the 2023–24 PBA 3x3 season, although the Converge FiberXers, Phoenix Super LPG Fuel Masters, and Rain or Shine Elasto Painters did not field a team. The Blackwater Bossing Red President changed their name into Blackwater Smooth Razor before the season. Two guest teams (Pioneer ElastoSeal Katibays and Wilcon Depot 3x3) participated, with Wilcon Depot 3x3 debuting this season, committing to play for at least one conference. Guest teams J&T Express and Platinum Karaoke, who both appeared during the previous season, took a leave of absence for this season.

Wilcon Depot 3x3 eventually became defunct after the first conference and was replaced by MCFASolver Tech Centrale starting from the second conference.

Format
The season's format will be highly similar to that of the previous season. The season will have three tournaments or conferences. Each conference will have six two-day legs and a grand final. The 11 teams will be divided into four pools, with pool A having three teams while pools B and C having four each. Teams within their pools will play in a single round-robin format. The top two teams of pool A and the top three teams of pools B and C will directly qualify for the quarterfinals. The knockout stage will be a single-elimination tournament and a third place game will also be held. The winner of each leg will receive ₱100,000, the runner-up will receive ₱50,000, while the third placed team will receive ₱30,000. The seedings and pool compositions for each leg will be based on the results of the preceding leg.

After six legs, the cumulative standings will be calculated and the top four teams will directly qualify for the quarterfinals of the Grand Finals. The fifth to tenth-placed teams will qualify for the preliminary round of the Grand Finals. The bottom teams will not qualify for the Grand Finals. The Grand Champion will receive ₱750,000, the runner-up will receive ₱250,000, while the third placed team will receive ₱100,000.

Starting this season, the games were played in various Ayala Malls branches. In the first two years of PBA 3x3, the games were held at different Robinsons Malls branches.
