Den is a fantasy comic book series by Richard Corben.

It is about the adventures of a young man who is whisked to a fantasy world named Neverwhere where he is changed into a naked muscled adventurer who is hunted by powerful forces, threatened by dangerous creatures and lusted by impossibly beautiful naked women.

This series was a major feature in the early Heavy Metal magazine in the late 1970s and it was adapted in a highly condensed fashion in the Heavy Metal animated film.

The Den saga originated from a 1968 short film entitled Neverwhere (the first graphic novel would share the same title), animated and produced by Corben at his native Calvin Studios in Kansas City.

The Den series was published in the following graphic novels and serials, in order:

• Neverwhere
• Muvovum
• Children Of Fire
• Dreams (compilation of smaller color Den comics)
• Elements (second compilation of further smaller color comics)
• DenSaga Vol 1-4
