The Paraibuna is a river in Minas Gerais state, Brazil, and a major tributary of the Paraíba do Sul. It flows through the important commercial and industrial city of Juiz de Fora. The name of the river probably comes from the Tupi "pará y b'una" signifying "great dark river". The Paraibuna has its source near Antônio Carlos in the Serra da Mantiqueira at an elevation of 1,200 metres. It then flows northwest to southeast for 166 kilometres and joins the Paraíba do Sul at an elevation of 250 metres.
