Its nine provinces are bounded to the south by 2,798 kilometres of coastline that stretches along the South Atlantic and Indian Ocean; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; to the east and northeast by Mozambique and Eswatini; and it encloses Lesotho.

Pretoria is the administrative capital, while Cape Town, as the seat of Parliament, is the legislative capital. Bloemfontein has traditionally been regarded as the judicial capital. The largest and most populous city is Johannesburg, followed by Cape Town and the busiest port city in sub-Saharan Africa, Durban.
