Underground Network is Anti-Flag's third studio album, released on Fat Wreck Chords in 2001. Widely considered to be the band's breakthrough album, it helped make Anti-Flag a household name in the U.S. punk scene with tracks such as "Underground Network," "Bring Out Your Dead," and "Stars and Stripes."

The title "This Machine Kills Fascists" pays tribute to folk-music hero Woody Guthrie, who had a guitar labeled with the same slogan.

Underground Network was removed from Spotify in 2023 following the several rape and sexual assault allegations made against Sane.
