The Cape Government Railways 0-4-0ST 1881 Coffee Pot was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.

In 1881, two Cape gauge saddle-tank locomotives with a 0-4-0 wheel arrangement were placed in service by Teague and Company, who operated Teague's Tramway at the Kimberley diamond mine. In March 1885, one of them was purchased by the Cape Government Railways for use as a construction locomotive, while the other was sold to the Kimberley Diamond Mine. The Railways locomotive was nicknamed the Coffee Pot while serving as construction engine at Norvalspont.
