The Namaqualand 0-6-2 Clara Class of 1890 was a South African steam locomotive from the pre-Union era in the Cape of Good Hope.

Between 1890 and 1898, four 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. Acquired to meet the traffic needs of the upper mountainous section of the railway, they became known as the Mountain type. The first three of these locomotives were later described as the Clara Class, while the fourth was included in this Class by some and included in the subsequent Scotia Class by others.^[1]
