Bryconidae, also known as bryconids, is a family of freshwater fishes belonging to the order Characiformes. They are native to South America. Some species reach particularly large sizes for characins, with Salminus franciscanus being one of the largest characiforms overall.

Genera:

• Family Bryconidae Eigenmann, 1912
  • Subfamily Bryconinae Eigenmann, 1912
    • Genus Brycon Müller & Troschel, 1844
    • Genus Chilobrycon Géry & de Rham, 1981
    • Genus Henochilus Garman, 1890
  • Subfamily Salmininae Cockerell, 1915
    • Genus Salminus Agassiz, 1829

The earliest known fossil member of this group is †Brycon avus (Woodward, 1898) from the Oligocene-aged Tremembé Formation of Brazil. A slightly older potential specimen of B. avus is also known from the Late Eocene/Early Oligocene of the Aiuruoca Basin.
