Attack of the Killer B's is a compilation album of B-sides, covers and rarities by the thrash metal band Anthrax and the band's last audio album released before vocalist John Bush replaced longtime Anthrax vocalist Joey Belladonna in 1992.

Though a collection of "B-sides", the album featured one of their biggest singles; a collaboration/cover of Public Enemy's "Bring the Noise".

The track "Startin' Up a Posse" is a tongue in cheek attack on the Parents Music Resource Center.

The compilation also includes covers of songs by Discharge, Kiss, Trust, and the surf rock staple "Pipeline", recorded by The Chantays.

"Bring the Noise" has been a live staple since Anthrax first played it on the Headbangers Ball Tour with Helloween and Exodus in 1989,[6] and it later appeared in the videogames Tony Hawk's Pro Skater 2 and WWE SmackDown!
