Miss South Africa 2018 was the 60th edition of Miss South Africa. It was held on 27 May 2018 at the Sun Arena at Time Square in Pretoria. It was simulcasted as a live broadcast on M-Net and Mzansi Magic, and was hosted by Bonang Matheba. For the first time, two separate delegates were selected to represent South Africa at Miss World and Miss Universe, but only one was crowned Miss South Africa.
Twenty eight semi-finalists from different provinces were selected from over nine hundred women who entered, but only twelve finalists were chosen to compete for the crown. During the live telecast, the Top 12 was narrowed to a Top 5 and then a Top 2. The Top 2 were awarded separate titles, Miss Universe South Africa, won by Tamaryn Green, and Miss World South Africa, won by Thulisa Keyi. Adè van Heerden of Western Cape crowned her successor Tamaryn Green of Western Cape at the end of the event. Green will go on to represent South Africa at Miss Universe 2018 while Keyi will represent South Africa at Miss World 2018
