Pescado Rabioso (Rabid Fish) was an Argentine rock band led by musician Luis Alberto Spinetta from 1971 to 1973.

Initially a trio accompanied by drummer Black Amaya and bassist Osvaldo "Bocón" Frascino, it became a quartet with the addition of keyboardist Carlos Cutaia.

In spite of its short life, Pescado Rabioso is still considered an important and influential piece of Argentine rock history.

It was the second major band of Spinetta, created after Almendra's break up in the late 1960s and a seven-month trip through Brazil, United States and Europe.

Although labeled under the band's name due to legal terms with his record company, Pescado Rabioso's final album Artaud is actually a complete solo effort from Spinetta.
