Port Elizabeth North was a constituency in the Cape Province of South Africa, which existed from 1929 to 1994.

The first challenge to the Cape Qualified Franchise came with the Women's Enfranchisement Act, 1930 and the Franchise Laws Amendment Act, 1931, which extended the vote to women and removed property qualifications for the white population only – non-white voters remained subject to the earlier restrictions.

In 1936, the Representation of Natives Act removed all black voters from the common electoral roll and introduced three "Native Representative Members", white MPs elected by the black voters of the province and meant to represent their interests in particular.

[1] When initially created, Port Elizabeth North was a safe seat for the South African Party – it won the first two elections in the seat unopposed, and (along with its successor the United Party) continued to win large majorities for the next twenty years.

In 1953, however, the seat fell to the National Party, which would hold it for the entire rest of its existence, usually by wide margins.
