The FIBA 3x3 World Tour is the pinnacle event of an 'open' network of FIBA-endorsed 3x3 tournaments. Any group of four players - regardless of their nationality and representing a city - can qualify for the FIBA 3x3 World Tour by taking part in a lower level/regional tournament, eventually making their way to the world stage.

Season 2018 consisted of nine Masters tournaments, before culminating with the FIBA 3x3 World Tour Final.

22 FIBA 3x3 Challenger tournaments were played in the season 2018.
