Sir Reginald Stephen Garfield Todd was a liberal Prime Minister of Southern Rhodesia from 1953 to 1958 and later became an opponent of white minority rule in Rhodesia.

The prime minister of Rhodesia was the head of government of Rhodesia. Rhodesia, which had become a self-governing colony of the United Kingdom in 1923, unilaterally declared independence on 11 November 1965, and was thereafter an unrecognized state until 1979. In December 1979, the country came under temporary British control, and in April 1980 the country gained recognized independence as Zimbabwe.
