Operation Ivy was an American punk rock band from Berkeley, California, formed in May 1987. They were critical to the emergence of Lookout Records and the so-called "East Bay Sound."

The band's name was derived from the Operation Ivy series of nuclear tests in 1952. Although the band released just one full-length album (Energy) before breaking up in May 1989, Operation Ivy is well remembered as the direct antecedent of popular band Rancid and for wielding a lasting stylistic influence over numerous other bands in what became the third wave ska movement.
