The CSA Provincial Competitions are three South African domestic cricket competitions run by Cricket South Africa (CSA). Three-day (first-class) and one-day (list-A) competitions were introduced for the 2004–05 season, while a Twenty20 competition was introduced for the 2011–12 season.
The CSA competitions are predominantly contested by South African provincial teams, the number of which has been fixed at thirteen since the 2007–08 season. A non-South African team, Namibia, has competed since the 2006–07 season, while two invitational teams from Zimbabwe competed in the early seasons. Prior to the introduction of the CSA competitions, the South African provincial teams competed in the Sunfoil Series (better known as the Currie Cup) and the domestic one-day tournament (known under various names). As part of a reorganisation of South Africa's domestic structure, the provincial teams were replaced in those competitions by six franchise teams, which are wholly professional.
