The Cape Copper Company 0-6-2 Scotia Class of 1900 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.

Between 1900 and 1905, six more Mountain type tender locomotives with a 0-6-2 wheel arrangement were placed in service by the Cape Copper Company on its two-foot six inch gauge Namaqualand Railway between Port Nolloth and O'okiep in the Cape of Good Hope. Later described as the Scotia Class, they were similar to the earlier Clara Class locomotives, but with shorter boilers, longer fireboxes and larger firegrates.

The Namaqualand Railway was constructed between 1869 and 1876 by the Cape Copper Mining Company, restructured as the Cape Copper Company in 1888. The railway from Port Nolloth on the West Coast to the copper mines around O'okiep was initially exclusively mule-powered, but in 1871 two 0-6-0T locomotives named John King and Miner were acquired by the mining company on an experimental basis. They were followed between 1886 and 1888 by three 0-4-0WT condensing locomotives, and from 1890 by four 0-6-2 Clara Class Mountain type tender locomotives.

Between 1900 and 1905, six more 0-6-2 tender locomotives of the Mountain type were delivered to the Cape Copper Company from Kitson and Company. Since the first three locomotives of the Clara Class suffered major problems with their fireboxes and tubes as a result of the poor quality of water in the region and tough working conditions, a fourth locomotive, no. 7 named Albion, had been delivered in 1898 with a shorter boiler to make room for a longer firebox in an effort to overcome these issues. These six new locomotives were a further development in the same direction, also with larger fireboxes, but with slightly longer boilers than no. 7 Albion, which resulted in boiler-and-firebox assemblies which were about a foot longer than those of the earlier locomotives.

These six locomotives were very similar in appearance to the earlier Clara Class, but could be visually identified by their steam domes which were located further forward, closer to their chimneys, as well as by the different shape of the cutaway at the rear of their frames above their trailing axles. They were named Scotia, Hibernia, Cambria, Canada, Australia and India respectively and were also numbered, in the range from 8 to 10, 12, 14 and 15. They were later described as the Scotia Class.
