The Witteberg or Witteberge is a South African mountain range just off the south-west corner of Lesotho. The range, which rises to 2408 metres, stretches for about 60 km (37 mi) from Lundin's Neck in the east to Lady Grey in the west. The range lends its name to the Witteberg Series, the uppermost fossiliferous sequence of the Cape System of sedimentary rocks in South Africa.
