The South African Railways Class 8Z 2-8-0 of 1904 was a steam locomotive from the pre-Union era in the Cape of Good Hope. In 1904, the Cape Government Railways placed its last eight 8th Class 2-8-0 Consolidation type steam locomotives in service. Most of its other 8th Class locomotives were built with a 4-8-0 Mastodon type wheel arrangement. In 1912, when they were assimilated into the South African Railways, these eight were renumbered and designated Class 8Z.
