The 1999 Tournament of the Americas, later known as the FIBA Americas Championship and the FIBA AmeriCup (also known as Las Americas Tournament for Men, the FIBA Americas Olympic Qualifying Tournament, or Panamerican Olympic Qualifying Tournament for Men), was a basketball championship hosted by Puerto Rico, from July 14 to July 25, 1999. The games were played in San Juan, at the Roberto Clemente Coliseum. This FIBA AmeriCup was to earn the two berths allocated to the Americas for the 2000 Olympics, in Sydney, Australia. The United States won the tournament, the country's fourth AmeriCup championship.
Eight teams qualified during the qualification tournaments held in their respective zones in 1999; two teams (USA and Canada) qualified automatically since they are the only members of the North America zone.
The top four teams in both Group A and Group B advanced to the quarterfinal group. Then each team played the four from the other group once to complete a full round robin. Records from the preliminary groups carried over.
