Tuna also called tunny, any of seven species of oceanic fishes, some very large, that constitute the genus Thunnus and are of great commercial value as food. They are related to mackerels and are placed with them in the family Scombridae. Tunas vary considerably, both within and among species.

Tuna, opah, and mackerel sharks are the only species of fish that can maintain a body temperature higher than that of the surrounding water. An active and agile predator, the tuna has a sleek, streamlined body, and is among the fastest-swimming pelagic fish – the yellowfin tuna, for example, is capable of speeds of up to 75 km/h (47 mph). Found in warm seas, it is extensively fished commercially, and is popular as a game fish. As a result of overfishing, stocks of some tuna species, such as the southern bluefin tuna, are close to extinction.
