B. M. Hertzog National General elections were held in South Africa on 12 June 1929.

Hertzog had the opportunity to form a government without the aid of the Labour Party.

In fact the Pact government continued, with two ministers from the Creswell Labour faction remaining in office.

The South Africa Act 1909 had provided for a delimitation commission to define the boundaries for each electoral division.

The figures in brackets are the number of electoral divisions in the previous (1923) delimitation.
