The South African Chess Championship was first organised in 1892 by the Cape Town Chess Club. It is now organised by Chess South Africa (CHESSA), the governing body of chess in South Africa. The tournament is normally held every two years. It is restricted to chess players resident in South Africa (although exceptions have been made on occasion) and participation is by invitation only.
CHESSA was formed in 1992, after unification talks between various chess bodies that commenced the previous year. The 1995 event, the first organised by CHESSA, included titled players from Angola and Zimbabwe and was run on the Swiss system. Since that date, the tournament has been held on a round-robin basis. The winner of the tournament holds the title of South African Closed Chess Champion until the next tournament is held.
Historically, the tournament was usually held on a round-robin or double round-robin basis. In case of a tie for first place, a playoff match was usually conducted. In the early days, the title holder could also be challenged to a title match, and these matches are tabled below.
