The Cape Government Railways 3rd Class 4-4-0 of 1883 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.
In 1882, the Cape Government Railways placed orders with Neilson and Company for eighteen 3rd Class tender locomotives with a 4-4-0 American type wheel arrangement. They were intended for fast passenger service on all three Cape Systems and were delivered early in 1883.
