The South African Railways Class 7 4-8-0 of 1892 is a steam locomotive from the pre-Union era in the Cape of Good Hope.

Under the Whyte notation for the classification of steam locomotives, 4-8-0 represents the wheel arrangement of four leading wheels on two axles, usually in a leading truck or bogie, eight powered and coupled driving wheels on four axles and no trailing wheels. In North America and in some other countries the type was usually known as the Twelve-wheeler.
