Vierfontein is a settlement in Fezile Dabi District Municipality in the Free State province of South Africa. Vierfontein is a coal-mining village, formerly associated to the Vierfontein Power Station, which was active from 1953 to 1990. When the power station was decommissioned, the village was sold to a property developer. The abandoned fuel station was used in the film "Orkney snork nie".

Directly translated to English from Afrikaans, the name literally means "four fountains".
