The 1998 FIBA World Championship was the 13th FIBA World Championship, the international basketball world championship for men's national teams. The tournament was organised by the International Basketball Federation (FIBA), and hosted in Greece from 29 July to 9 August 1998. It was contested by 16 nations, with matches held at two venues, in Athens and Piraeus.
There were 16 teams taking part in the 1998 World Cup of Basketball. After the 1996 Olympics, the continental allocation for FIBA Americas was reduced by one when the United States won the Olympic tournament, automatically qualifying them for the 1998 World Cup.
Host nation: 1 berth
1996 Summer Olympics: 12 teams competing for 1 berth, removed from that country's FIBA zone.
The top three teams in each group advance to the second round, into either Group E or F. The fourth place team in each group moves onto the 13th–16th classification.
