The South African type SH tender was a steam locomotive tender from the pre-Union era in the Natal Colony.

The Type SH tender first entered service in 1904, as tenders to the Class B 4-8-0 Mastodon type steam locomotives which were acquired by the Natal Government Railways in that year. These locomotives were designated Class 1 on the South African Railways in 1912.

Type SH tenders were built in 1904 by the North British Locomotive Company.

The Natal Government Railways (NGR) placed fifty Class B Mastodon type locomotives in service in 1904. The locomotive and tender were designed by NGR Locomotive Superintendent D.A. Hendrie. Known as the Hendrie B, the first tender locomotive to enter service on the NGR in quantity, it replaced the NGR's fleet of tank locomotives on mainline working. The Type SH tender first entered service as tenders to these locomotives.

In 1906, six of the Hendrie B engines were modified to a 4-8-2 Mountain type wheel arrangement.

As built, the tender had a coal capacity of 6 long tons (6.1 tonnes) and a water capacity of 3,225 imperial gallons (14,700 litres), with a maximum axle load of 9 long tons 10 hundredweight 2 quarters (9,678 kilograms).

Apart from those delivered with the Class B Mastodon type locomotives, more Type SH tenders entered service in 1905 as tenders to the NGR Class A Pacific type locomotive, or Hendrie A.

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 often also the 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.

The SAR grouped and renumbered the Hendrie A and Hendrie B locomotives into three separate Classes, according to wheel arrangement. Bearing in mind that tenders could and did migrate between engines, the Type SH tenders should have been numbered in the number ranges as shown.
