Immaterial is a collection of horror stories by Australian horror writer Robert Hood.

Immaterial collects fifteen tales featuring ghosts and grue in plenty, aptly demonstrating his range of concerns and effects.

In 2001 Bill Congreve approached Hood with the idea of putting together a retrospective-style collection of his works.
