The South African Railways Class 6Y 2-6-2 of 1903 was a steam locomotive from the pre-Union era in the Cape of Good Hope.

In 1903, the Cape Government Railways placed two 6th Class steam locomotives with a 2-6-2 Prairie type wheel arrangement in service. In 1912, when these locomotives were assimilated into the South African Railways, they were renumbered and designated Class 6Y.
