The Mbuluzi River is one of the main rivers of Eswatini, and an important river in Mozambique. On the boundary of these countries, the Mbuluzi cuts through the Lebombo Range, before entering the Mozambican plain. It empties into the Estuário do Espírito Santo and then Maputo Bay at Maputo, and its waters pass under the Maputo–Katembe bridge, completed in 2018.
