The South African National Basketball Club Championship is the national championship for premier basketball teams in South Africa. The winner of the national championship qualifies for the qualifying tournaments of the Basketball Africa League (BAL). The privately organised Basketball National League (BNL) is considered the de facto top level basketball league in the country, and has had a representative in some seasons.
The competition is organised by Basketball South Africa, the national basketball federation, since 2021.
The competition was not held in 2023, but returned in 2024.
Each team is allowed to register a maximum of 20 players, of which 4 can be foreign players. In the first four tournaments, 4 teams participated. In 2025, the tournament expanded to 9 teams with two groups and a final stage.
