The South African type MT tender was a steam locomotive tender.

Type MT tenders entered service between 1928 and 1945, as tenders to the Classes 12A, 19B, 19C and 19D 4-8-2 Mountain type steam locomotives which were placed in service by the South African Railways during that period.

Type MT tenders were built between 1928 and 1945 by Berliner Maschinenbau, Borsig Lokomotiv Werke, Henschel and Son, Friedrich Krupp AG, North British Locomotive Company (NBL), Robert Stephenson and Hawthorns, and Škoda Works.

The South African Railways (SAR) placed 67 Class 12A 4-8-2 Mountain type locomotives in service between 1919 and 1929, built by North British and Henschel. The engines were designed by D.A. Hendrie, Chief Mechanical Engineer (CME) of the SAR from 1910 to 1922. The locomotives were delivered in five batches and with two tender types, the Type MP1 in 1919 and 1921 and the Type MT in 1928 and 1929. The design of the Type MT tender was by Hendrie's successor, Colonel F.R. Collins DSO, the CME from 1922 to 1929.

The official SAR tender diagrams show the Type MT tender as having first entered service in 1919, but builder's pictures of the North British-built Class 12A no. 1520 of 1919 and no. 2111 of 1921 show them with Type MP1 tenders. Builder's pictures of Henschel-built Class 12A no. 1543 of 1928 and North British-built no. 2131 of 1929 show the engines with Type MT tenders. It would therefore appear that Type MT tenders first entered service in 1928, not 1919.
