The South African type XM2 tender was a steam locomotive tender from the pre-Union era in Transvaal.

The Type XM2 tender entered service in 1904, as tenders to the Class 10 4-6-2 Pacific type and Class 11 2-8-2 Mikado type steam locomotives which were acquired by the Central South African Railways in that year. In 1912, both locomotive types retained their Class designations on the South African Railways.

Type XM2 tenders were built between 1904 and 1912 by Beyer, Peacock and Company, North British Locomotive Company and Vulcan Foundry. More Type XM2 tenders were subsequently ordered from Robert Stephenson and Company.

The Central South African Railways (CSAR) placed 15 Class 10 Pacific type and 36 Class 11 Mikado type locomotives in service in 1904. Both locomotives and the tender were designed by P.A. Hyde, Chief Locomotive Superintendent of the CSAR.

The Type XM2 first entered service as tenders to these two locomotive Classes. The Class 10 was acquired to work the passenger trains on the Natal and Cape mainlines out of Johannesburg, while the Class 11 entered service on the Reef to haul coal between Germiston and Witbank.

The tender had a coal capacity of 10 long tons (10.2 tonnes) and a water capacity of 4,000 imperial gallons (18,200 litres), with a maximum axle load of 12 long tons 11 hundredweight (12,750 kilograms).

In the South African Railways (SAR) years, tenders were numbered for the engines they were delivered with. In most cases, an oval number plate, bearing the engine number and tender type, would be attached to the rear end of the tender. During the classification and renumbering of locomotives onto the SAR roster in 1912, no separate classification and renumbering list was published for tenders, which should have been renumbered according to the locomotive renumbering list.
