The Cape Government Railways 4th Class 4-6-0TT of 1880 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.
In 1880 and 1881, the Cape Government Railways placed eighteen 4th Class 4-6-0 tank-and-tender locomotives in mainline service on its Midland and Eastern Systems, working out of Port Elizabeth and East London respectively. It was the first South African locomotive to be built to a local design. Four of these locomotives were still in service to come onto the South African Railways roster in 1912.
