The Catholic hierarchy of South Africa is entirely Latin, composed of five ecclesiastical provinces, each under a Metropolitan Archbishop, with a total of 20 suffragan South African dioceses and an exempt pre-diocesan apostolic vicariate, as well as three suffragans (two dioceses, one apostolic vicariate) from below-mentioned neighbor states (fellow former British colonies).
Botswana has only one diocese and one apostolic vicariate, both suffragan of the South African Metropolitan Archbishop of Pretoria.
Swaziland only has a single diocese, suffragan of the South African Metropolitan of Johannesburg.
None of them has an Eastern Catholic jurisdiction, only South Africa has an exempt Military ordinariate.
There also is an Apostolic Nunciature to South Africa as papal diplomatic representation at embassy-level in the national capital Pretoria.
