Do Singapore passport holders need a visa to visit South Africa?

No visa needed. Singapore ordinary passport holders can enter South Africa visa-free for tourism for up to 90 days. Singapore is on South Africa's official visa-exemption list. Holders of an ordinary Singapore passport may enter and stay in South Africa visa-free for up to 90 days per visit for tourism or business, with no application or fee required. The exemption is confirmed by the South African Department of Home Affairs (DHA) Visa Exemption List, which lists Singapore (Republic of) ordinary passports at 90 days with no 30-day fee restriction, and by the Singapore High Commission in Pretoria. On arrival you simply present your passport to an immigration officer, who decides the actual length of stay granted (up to 90 days) based on the purpose of your visit. Your passport must be valid for at least 6 months beyond your date of entry and have at least 2 blank pages. Officials may ask for proof of a return or onward ticket, accommodation, and sufficient funds. There is no eVisa, no visa-on-arrival paperwork, and no electronic travel authorization required for this short-stay visit.
