The Apies River is a river that flows through the city of Pretoria, South Africa. Its source is located just south of the city (south of Erasmus Park) and it flows northward until it drains into the Pienaars River.
The river is known as the Apiesrivier in Afrikaans (in which "Apies" means "small monkeys").
Nguni-speaking settlers, who became known as the Ndebele, are thought to have been the first people to recognise the suitability of the Apies River valley as a place to put down roots. They named the river after one of the chiefs, Tshwane (“little ape”), which was later translated into the Afrikaans “Apies”. The river is - to a large extent - canalised with little resemblance of the natural river reach of the past. The river reach between Wonderboom Poort and the Bon Accord Dam is, however, not canalised.
