General elections were held in South Africa on 30 March 1966. The result was another comprehensive victory for the National Party under H. F. Verwoerd.

The election marked a major strengthening of power for the ruling NP, which gained a two-thirds majority in parliament for the first time. The main opposition United Party slightly increased its share of the popular vote, but nevertheless saw its parliamentary representation considerably reduced.

The number of House of Assembly seats for White voters in South Africa had been increased from 150 to 160 by the Constitution Amendment Act of 1965. In addition, there were six seats for White voters from South-West Africa (now Namibia). There were also four seats reserved for Coloured representatives, who did not have to stand for re-election during 1966.

On 6 September, several months after the election, Prime Minister Verwoerd was assassinated.
