The Sand River or Polokwane River (Afrikaans: Sandrivier) is a watercourse in Limpopo Province, South Africa, a right hand tributary of the Limpopo River. Its new name "Polokwane River" is homonymous with the name of the town of Polokwane, formerly Pietersburg, about 200 kilometres (120 mi) upriver from its mouth. The Sand River flows by the western edge of this town.
