The skipjack tuna, Katsuwonus pelamis, is a medium-sized perciform fish in the tuna family, Scombridae. It is otherwise known as the aku, arctic bonito, mushmouth, oceanic bonito, striped tuna, or victor fish. It grows up to 1 m in length.

It is a streamlined, fast-swimming pelagic fish, common in tropical waters throughout the world, where it inhabits surface waters in large shoals (up to 50,000 fish), feeding on fishes, crustaceans, cephalopods and mollusks. It is an important prey species for large pelagic fishes and sharks.

It is an important commercial and game fish, usually caught using purse seine nets, and is sold fresh, frozen, canned, dried, salted, and smoked.

In Japanese cuisine, skipjack tuna is known as katsuo, and is commonly smoked and dried to make katsuobushi, an important ingredient in making dashi (fish stock).
