The Komati River, also known as the Inkomati River or Incomati River, is a river in South Africa, Eswatini and Mozambique. Originating in north-western Eswatini, it is joined by the Crocodile River in the Lebombo Mountains, enters far south-western Mozambique below the border town of Komatipoort, and enters the Indian Ocean around 24 km (15 mi) north-east of Maputo.

Komatipoort is a town situated at the confluence of the Crocodile and Komati Rivers in Mpumalanga province, South Africa. The town is 8 km from the Crocodile Bridge Gate into the Kruger Park, and just 5 km from the Mozambique border and 65 km from the Eswatini border.
