Villiersdorp is a town of approximately 10,000 people located in the Western Cape province of South Africa in the Overberg region.

Unlike most of the geographical region which specialises in wheat and canola farming, the Villiersdorp Valley is now agriculturally and in micro-climate more similar to the Elgin Valley and Grabouw since the building of the Theewaterskloof Dam, and thus also specialises in deciduous fruit farming and viticulture.

The Theewaterskloof Dam, the largest dam in the Western Cape and seventh largest in South Africa and important water supply to Cape Town fills the majority of the valley floor.

The Villiersdorp Co-Op is also the only place in South Africa that processes and dries persimmons.

The town is named after Field Cornet Pieter de Villiers, a local farmer who founded the settlement in 1843.
