Last Warning is a compilation album by New York hardcore band Agnostic Front.

The first eleven tracks—often consisting of two songs strung together—were recorded live in December 1992 at CBGB in New York City.

The remainder of the CD is the band's 1983 7-inch EP, United Blood.

It contrasts the later crossover thrash style the band had adopted in later releases with the raw New York hardcore style of their debut release.

All songs written by Agnostic Front, except for "Crucified" (Iron Cross).
