The South African Railways Class 6J 4-6-0 of 1902 was a steam locomotive from the pre-Union era in the Cape of Good Hope. In 1902, fourteen 6th Class bar framed steam locomotives with a 4-6-0 wheel arrangement were placed in service by the Cape Government Railways. In 1912, when they were assimilated into the South African Railways, they were renumbered and designated Class 6J.
