In basketball, an official enforces the rules and maintains order in the game. The title of official also applies to the scorers and timekeepers, as well as other personnel that have an active task in maintaining the game. Basketball is regarded as among the most difficult sports to officiate due to the speed of play, complexity of rules, the case-specific interpretations of rules, and the instantaneous decision required.

The International Basketball Federation is an association of national organizations which governs the sport of basketball worldwide. FIBA defines the rules of basketball, specifies the equipment and facilities required, organizes international competitions, regulates the transfer of athletes across countries, and controls the appointment of international referees. A total of 212 national federations are members, organized since 1989 into five zones: Africa, Americas, Asia, Europe, and Oceania.
