The 2023 FIBA Basketball World Cup will be the 19th tournament of the FIBA Basketball World Cup for men's national basketball teams. The tournament will be the second to feature 32 teams. For the first time in its history, the World Cup will be hosted by multiple nations in Asia, the Philippines, Japan, and Indonesia, from 25 August to 10 September 2023.
It is the first World Cup to be hosted in Indonesia, and the second to be hosted in both the Philippines and Japan since they first hosted the tournament in 1978 and 2006, respectively. The tournament will also be the second straight to be held in Asia after China's hosting of the 2019 edition. It will also mark the first time in the history of the FIBA Basketball World Cup that a host nation has not qualified.
The tournament will serve as qualification for the 2024 Summer Olympics, where the top two teams from each of the Americas and Europe, and the top team from each of Africa, Asia and Oceania, will qualify alongside the tournament's host France.
Spain will be the defending champions, having beaten Argentina in the 2019 final.
80 teams from four FIBA zones qualified for the World Cup qualifiers through qualification for the FIBA Continental Cups (AfroBasket 2021, 2022 FIBA AmeriCup, 2022 FIBA Asia Cup, and EuroBasket 2022). For Europe and the Americas, additional teams qualified through the pre-qualifiers of the said regions. The participants of both the AfroBasket and the Asia Cup comprise the teams that will also take part in the qualifiers for their respective regions. The first game of the qualifiers took place in Minsk on 25 November 2021 between Belarus and Turkey, as part of the European Qualifiers. The draw for the World Cup qualifiers was held at the Patrick Baumann House of Basketball in Mies, Switzerland, on 31 August 2021.

Venues
Five venues from five host cities will host matches for the 2023 FIBA Basketball World Cup. Three cities in the Greater Manila Area will host four Preliminary Round Groups, two Second Round Groups, and the Final tournament phase from the Quarterfinals onwards. On the other hand, Okinawa and Jakarta will each be host to two Preliminary Round Groups and one Second Round Group. The Philippines will host 16 teams while Japan and Indonesia will host 8 teams each.Qualification
As co-hosts, the Philippines and Japan each got an automatic qualification for the tournament when they were awarded the joint hosting rights along with co-host Indonesia. However, Indonesia's host qualification slot was conditional as FIBA wanted the Indonesian national team to be competitive by 2021 and thus required Indonesia to qualify for and finish in the top-eight (advance to the quarter-finals) of the 2022 FIBA Asia Cup (postponed from 2021). Indonesia officially qualified for the Asia Cup as host and advanced from the preliminary round-robin round, but lost to China in the playoff round (round of 16) and were therefore unable to secure qualification for their hoped-for FIBA Basketball World Cup debut. This is the first time in the history of the FIBA Basketball World Cup that a host nation has not qualified.80 teams from four FIBA zones qualified for the World Cup qualifiers through qualification for the FIBA Continental Cups (AfroBasket 2021, 2022 FIBA AmeriCup, 2022 FIBA Asia Cup, and EuroBasket 2022).
