Thunnus is a genus of ocean-dwelling, ray-finned bony fish from the mackerel family, Scombridae.

This genus has eight species:

  • Albacore, T. alalunga (Bonnaterre, 1788)
  • Southern bluefin tuna, T. maccoyii (Castelnau, 1872)
  • Bigeye tuna, T. obesus (Lowe, 1839)
  • Pacific bluefin tuna, T. orientalis (Temminck & Schlegel, 1844)
  • Atlantic bluefin tuna, T. thynnus (Linnaeus, 1758)
  • Yellowfin tuna, T. albacares (Bonnaterre, 1788)
  • Blackfin tuna, T. atlanticus (Lesson, 1831)
