The following are minor characters from Berkeley Breathed's comic strip Bloom County. Though significant enough to have appeared multiple times in the strip, they were not crucial to the strip's overall development, and disappeared without much (if any) explanation long before Breathed segued into his next comic, Outland.

Though the strip's various compilations do not do them justice, the original cast of characters in Bloom County were Milo, Bess, and Major Bloom, along with a basset hound named "Rabies" whose thoughts could be read à la Snoopy; the first year of strips are mysteriously omitted from all compilations save the Bloom Library, although a selection did find publication in a 1986 anthology collection Bloom County Babylon: Five Years of Basic Naughtiness. Most of the strip's most memorable characters debuted later on, with Milo being the only key character to appear for the duration of the strip's run.
