Ferdinand Hartzenberg (8 January 1936 – 12 March 2021) was a South African politician and the second and last leader of the Conservative Party in South Africa between 1993 and its merger with the Freedom Front in 2004. He obtained a DSc (Agriculture) from the University of Pretoria. Hartzenberg became leader of the CP after Treurnicht's death in April 1993. This made him leader of the official opposition in the white chamber of the South African Parliament, a position he held until the first non-racial elections in April 1994.
