The 1959 FIBA World Championship was the 3rd FIBA World Championship—the international basketball world championship for men's national teams. It was hosted by Chile from 16 to 31 January 1959. Amaury Antônio Pasos was named the MVP.
The final games were supposed to be conducted at the newly constructed Metropolitan Indoor Stadium, but because the venue was not finished in time, competition was postponed by a year from the original date. Organizers moved outdoors to the Estadio Nacional de Chile, where the events were watched at by a crowd of at least 16,000.
Preliminary round: Three groups of four teams play each other once; top two teams progress to the final round, bottom two teams relegated to classification round.
