2023–24 PBA season

The 2023–24 PBA season, or PBA Season 48, is the 48th season of the Philippine Basketball Association.

Due to the participation of Philippine men's national basketball team in the 2023 FIBA Basketball World Cup and 2022 Asian Games, the PBA season started on November 5, 2023 and would only have two conferences, first being the Commissioner's Cup, followed by the season-ending Philippine Cup.

Opening day was originally scheduled on October 15, but was moved three weeks past the original date to give the players that participated in the 2023 FIBA Basketball World Cup and the 2022 Asian Games time to rest and recover.

The first activity of the season was the PBA Season 48 draft, held on September 17.

Executive board

 * Commissioner: Willie Marcial
 * Chairman: Ricky Vargas (Representing TNT Tropang Giga)
 * Vice-Chairman: Demosthenes Rosales (Representing Terrafirma Dyip)

Teams
Changes from previous season:
 * Chun Yu Bay Area Dragons, franchise team for the East Asia Super League, were to return to play in the Commissioner's Cup as a guest team, having played in the same conference during the previous season. However, they were disbanded prior to the start of the first conference.

Arenas
Under the new normal, the PBA has resumed playing in venues in Metro Manila and Rizal. The PBA also released its schedule showing its first "out-of-town" games since the pandemic, with five game days held in the provinces.

Retirement

 * On May 12, 2023, Reynel Hugnatan formally retired after being signed by the Meralco Bolts as one of its assistant coaches. Hugnatan played for three teams in his 19 seasons in the league.

Rule changes
The PBA competition committee approved the rule changes for implementation starting in the Commissioner's Cup games:

Pre-season

 * Several players were sanctioned by their respective teams and the PBA due to numerous ligang labas infractions.
 * Due to the long off-season, the PBA launched the "PBA on Tour", a months-long series of preseason games involving all PBA teams to be played across the country. Each team played 11 games and were allowed to have 17 players in their roster (but only 16 are allowed to play in a game) which are composed of their regular players, their 3x3 affiliate team players, free agents, and rookie aspirants. The tour started on May 21 and ended on July 30, 2023. There was no playoffs nor a championship series. The Magnolia Hotshots finished the tour with the best record, winning all of their 11 games.
 * The PBA competition committee proposed several rule changes, most notably the addition of the head coach challenge. The proposed new rules were first implemented during the PBA on Tour. After the tour, the league will assess which rules will be adapted starting the regular season.
 * Willie Marcial will remain as the league's commissioner until the 2026–27 season as his contract was extended by the PBA Board of Governors.
 * The PBA Board of Governors relaxed its rules regarding draft-eligible players who refuse to enter the draft and active PBA players who leave the league to play in another league locally or internationally. These players are no longer required to "sit out" seasons prior to joining the PBA. The former rule sanctioned these players by barring them from playing in the PBA for at most five years. Foreign-born Filipinos older than 30 years old are also now allowed to join the draft.
 * The East Asia Super League disbanded the Bay Area Dragons on September 1, 2023, reportedly due to financial reasons. The EASL mentions "conflict of interest" for managing a team and organizing the league at the same time, as the official reason for dissolving the club.
 * The PBA entered into an acquired agreement with ZOE Broadcasting Network and ABS-CBN Corporation to air the league's games on A2Z. All the ABS-CBN programs were temporarily affected by the changes in programming; A2Z's primetime, afternoon and weekend programming are preempted to give way for the PBA games on Wednesdays, Fridays and Sundays.    Previously, the games were formerly broadcast on TV5.

Commissioner's Cup

 * NorthPort Batang Pier team manager Pido Jarencio was fined ₱20,000 for hurling verbal threats at NLEX Road Warriors import Thomas Robinson during a elimination round game between the two teams.
 * TV5 Network, Inc. entered into an acquired agreement with Nine Media Corporation (NMC) to broadcast select PBA games on CNN Philippines every Saturday and Sunday.
 * Starting from the finals, all games were aired by RPTV, the channel that replaced the aforementioned and now defunct CNN Philippines. Games were still shown on A2Z but on a delayed basis. Eventually, A2Z also stopped broadcasting PBA games after game 5 of the finals.
 * The league fined Converge FiberXers' Mac Tallo ₱100,000 and Phoenix Super LPG Fuel Masters' Chris Lalata ₱50,000 for ligang labas infractions. The FiberXers also subsequently terminated Tallo's contract.
 * Magnolia Hotshots' Calvin Abueva was fined ₱100,000 for doing mocking gestures towards San Miguel Beermen's head coach Jorge Gallent during game 2 of the Finals.

Philippine Cup

 * March 31: Magnolia Hotshots' Calvin Abueva was fined ₱20,000 on flashing a dirty finger.
 * April 3: The Rain or Shine Elasto Painters wore their throwback 2006 Welcoat Dragons jerseys for the first time. The retro jerseys were worn to honor the first brand the franchise carried from their days participating at the defunct Philippine Basketball League and their first two seasons in the PBA.
 * June 1: The league announce that the operations of the PBA 3x3 will be indefinitely suspended.

Opening ceremonies
The opening ceremony for this season was held at the Araneta Coliseum in Quezon City on November 5, 2023. It was hosted by comedians Jose Manalo and Wally Bayola, in-character as their respective E.A.T. characters Mayor Jose Manalo and Dabarguard Wally, respectively. P-pop boy band Alamat were among the guest performers. The PBA Leo Awards for the 2022–23 season were held before the opening ceremonies.
