The Cape Government Railways 3rd Class 4-4-0 of 1901 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.

In 1901, the Cape Government Railways placed another six 3rd Class Wynberg Tender locomotives with a 4-4-0 American type wheel arrangement in suburban service in Cape Town. It was a heavier and more powerful version of the 3rd Class locomotive of 1898.
