Die '''Suid-Afrikaanse Klas 7B 4-8-0''' van 1900 is 'n [[Suid-Afrikaanse]] [[stoomlokomotief]] van die voor-Unie era in die Transvaal.

In 1900 het die Imperiale Militêre Spoorweë vyf-en-twintig Kaapse 7de Klas 4-8-0 Mastodon-tipe stoomlokomotiewe in diens geplaas. In dieselfde jaar, is drie Kaapse 7de Klas lokomotiewe wat deur die [[Pretoria-Pietersburg spoorlyn|Pretoria-Pietersburg Spoorweg]] bestel is, ook in diens geplaas. Al hierdie lokomotiewe is op die [[Sentraal-Suid-Afrikaanse Spoorweë]] se rooster geplaas aan die einde van die [[Tweede Vryheidsoorlog]] in 1902. In 1906 is drie van hierdie lokomotiewe aan die [[Natalse Regeringspoorweë]] verkoop.<ref name="Holland 1"/><ref name="Holland 2"/><ref name="Paxton-Bourne"/>
