Tesselaarsdal (formerly Teslaarsdal) is a dispersed rural settlement in the Theewaterskloof Municipality, Western Cape, South Africa.

It is situated on the northern side of the Kleinrivier Mountains, 20 kilometres (12 mi) south of the town of Caledon.

[1] The farm Hartebeesterivier was granted in 1781 to Johannes Jacobus Tesselaar as payment for his military service for the Dutch East India Company (VOC).

Ownership of land within the settlement was handled informally, with subdivisions and transfers not registered with government authorities.

In 1971 the Caledon Divisional Council approached the Cape Supreme Court to determine legal ownership of the farm, but the case was rejected.
