South Africa at the 1908 Summer Olympics

South Africa competed at the 1908 Summer Olympics in London, United Kingdom. At the time, South Africa consisted of four separate British colonies — the Cape Colony, Natal Colony, the Orange River Colony and the Transvaal Colony; they would form the Union of South Africa in 1910. At the 1908 Olympics, the South African team competed under a flag described as "the Red Ensign with a springbok in the corner."

Hurdler Doug Stupart carried the flag at the opening ceremony.
