The South West African 2-8-0T of 1907 was a steam locomotive from the German South West Africa era.

Between 1907 and 1910, the Lüderitzbucht Eisenbahn (Lüderitzbucht Railway) in German South West Africa placed 23 tank locomotives with a 2-8-0 Consolidation type wheel arrangement in service. After the First World War, when all railways in the territory came under the administration of the South African Railways in 1922, four of these locomotives still survived. They were not classified or renumbered but were simply referred to as the Eight-Coupled Tanks.[1][2][3]
