The 2020 FIBA Men's Olympic Qualifying Tournaments involved four basketball tournaments contested by 23 national teams, and the top teams earned a place in the 2020 Summer Olympics basketball tournament. They were originally scheduled to take place from 23 to 28 June 2020 but were postponed due to the COVID-19 pandemic, to 29 June to 4 July 2021.
The cities of Victoria, Split, Kaunas and Belgrade hosted the tournaments.
There were four qualifying tournaments, each producing a team which was qualified for the 2020 Summer Olympics. The format consisted of 24 national teams divided into four tournaments of six teams each, with the winning team from each event qualifying for the Olympics.
The FIBA Olympic Qualifying Tournaments included the 16 best-placed non-qualified teams from the 2019 FIBA Basketball World Cup and the two highest-ranked countries per region in the FIBA World Ranking. On 19 September 2019, FIBA announced those teams, which are Angola and Senegal (Africa), Mexico and Uruguay (Americas), China and Korea (Asia-Oceania), and Croatia and Slovenia (Europe).
New Zealand initially qualified for the Olympic Qualifying Tournament by virtue of the 2019 FIBA Basketball World Cup. On 26 February 2021, Basketball New Zealand announced that they would pull out of the tournament. On the same day, FIBA announced that they would be replaced by the Philippines as the next-best team from the Asia-Oceania region in the FIBA World Rankings.
Senegal had been initially included in the Belgrade Tournament, but it was forced to withdraw before the start due to several COVID-19 positive cases, and not being replaced by any team, lowering the number of participants to 23.
