Bloom County Babylon: Five Years of Basic Naughtiness is the fourth collection of the comic strip series Bloom County by Berkeley Breathed.

[1] It is preceded by Penguin Dreams and Stranger Things and followed by Billy and the Boingers Bootleg.

As a large-format anthology, about half of the book consists of abbreviated storylines from previous collections (Loose Tails, Toons For Our Times, and Penguin Dreams and Stranger Things), as well as some strips from Bloom County's first year that do not appear in any other collection.

The second half of the book contains a year's worth of strips that are not available in any smaller collection.

In addition to the strips, Bloom County Babylon also features a short illustrated prose story, "The Great LaRouche Toad-Frog Massacre."
