Basketball competitions at the 2019 Pan American Games in Lima, Peru began on July 27 and continue through August 10. The competitions are taking place at the Coliseo Eduardo Dibos. This was the Pan American Games debut of 3x3 basketball for both men and women, bringing the total number of basketball events on the program to four. This was done after the International Olympic Committee added the events to the program of the 2020 Summer Olympics in Tokyo, Japan. A total of eight men's and eight women's teams (each consisting of up to twelve athletes) competed in each five-a-side tournament respectively, and six teams competed in each 3x3 tournament (with four athletes per team). This means a total of 240 athletes are scheduled to compete.
