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. Finally, David Lebón replaced Frascino in 1972 and featured on the album Pescado 2.

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.
