The South African Railways Class C 4-6-0T of 1879 was a steam locomotive from the pre-Union era in the Colony of Natal.
Between 1879 and 1885, the Natal Government Railways placed thirty-seven 4-6-0 Ten-wheeler type tank steam locomotives in service. Of these, the first seven were built as 2-6-0T Mogul type locomotives and were subsequently modified to a 4-6-0T wheel arrangement. By 1908 they were designated Class G and in 1912, when some of the survivors were assimilated into the South African Railways, they were renumbered and reclassified to Class C. These were the oldest pre-Union locomotives to be classified and renumbered onto the SAR roster.
