The South African Railways Class 6L 4-6-0 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 two 6th Class 4-6-0 bar-framed steam locomotives in service. In 1912, when they were assimilated into the South African Railways, they were renumbered and designated Class 6L.
