The Cape Government Railways 5th Class 4-6-0 of 1891 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope. In 1891, the Cape Government Railways placed a second batch of thirty 5th Class tender locomotives with a 4-6-0 Tenwheeler type wheel arrangement in mainline service on all three Cape Systems. They were similar to the previous batch of 1890, but differed in respect of the diameter of their coupled wheels, the length of their smokeboxes and their tractive effort.
