The Letaba River (Afrikaans: Letabarivier), also known as Leţaba, Lehlaba or Ritavi, is a river located in eastern Limpopo Province, South Africa. It is one of the most important tributaries of the Olifants River.

Course

It starts at the confluence of the Groot Letaba River and Klein Letaba River, whence they continue their journey eastwards through the Lowveld as the Letaba River. It joins the Olifants River in the foothills of the Lebombo Mountains, near South Africa's border with Mozambique. In Mozambique the latter river is called the Rio Elefantes.
