Jan Kempdorp is an agricultural town situated in the centre of the Vaalharts Irrigation Scheme in the Northern Cape province of South Africa.

During the Second World War it was the site of a concentration camp housing German men regarded as potentially dangerous by the authorities.

The first settlers bought plots in 1938, and the town was proclaimed in 1953 and named after General Jan Kemp, a former Minister of Lands.

[2] When new provincial boundaries were drawn in 1994, Jan Kempdorp was still divided, now between the Northern Cape and North West provinces.

During South Africa's Border War Jan Kempdorp was the location of a munitions store, guarded 24 hours a day by National Servicemen who were first required to be of a lowered medical classification.
