Salminus, popularly known as dorado or dourado, is a genus of relatively large (up to 1.3–1.4 m or 4.3–4.6 ft long), predatory freshwater fish from the family Bryconidae, of which they are the only members of the subfamily Salmininae. They are native to large tropical and subtropical rivers in South America, and undertake migrations during the rainy season to spawn. They are very popular among recreational anglers and also support important commercial fisheries.

Significant taxonomic confusion has surrounded this genus, and until a review in 1990, several additional species were recognised (most of these are junior synonyms of S. brasiliensis). Although known for more than 150 years, S. franciscanus was only scientifically described in 2007. The following valid species are recognised:
