The South West African Zwillinge 0-6-0T of 1898 was a narrow gauge steam locomotive from the German South West Africa era.

0-6-0 is the Whyte notation designation for steam locomotives with a wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles, and no trailing wheels. Historically, this was the most common wheel arrangement used on both tender and tank locomotives in versions with both inside and outside cylinders.
