Crumbsuckers was an American crossover thrash band formed by bass player Gary Meskil in 1982, in Baldwin, Nassau County, New York.

Crumbsuckers amalgamated thrash and hardcore punk sounds and themes, making an immediate impact on the wider scene with their 1986 debut album, Life of Dreams.

Though the band was supported by its fanbase and fellow artists, Crumbsuckers' second album, Beast on My Back, failed to deliver on expectations, despite the musicianship displayed on the recording. The departure of lead vocalist Chris Notaro in 1988 started the band's gradual decline, despite the Crumbsuckers attempts to create a new identity. Even so, the band had already firmly cemented themselves as pioneers of the crossover thrash movement.

Crumbsuckers played its latest reunion show (with Chris Notaro on vocals) at the 2015 Black N' Blue Bowl Festival at Webster Hall (formerly the Ritz) in New York City on May 17, 2015.
