Dikwillem (Afrikaans) or Dicker Wilhelm (German), also known as Garub-Berg[1] or Garubberg, is a mountain in Namibia.

[2] With an elevation of 1496 meters and lying within the Namib desert, the mountain is visible from a great distance from all directions.

The harsh environment and barren plains around Garub[3] became the habitat of the desert horses of the Namib - descendants from German cavalry horses and adapted to the conditions and dry climate of the desert.

During the time of German colonial empire a heliographic station was operated by the German Schutztruppe on top of Dikwillem.
